Ladakh ("land of high passes") is a region in the Indian state of Jammu and Kashmir that currently extends from the Siachen Glacier in the Karakoram range to the main Great Himalayas to the south, inhabited by people of Indo-Aryan and Tibetan descent. It is one of the most sparsely populated regions in Jammu and Kashmir and its culture and history are closely related to that of Tibet. Ladakh is renowned for its remote mountain beauty and culture.Historically, the region included the Baltistan (Baltiyul) valleys (now mostly in Pakistan), the entire upper Indus Valley, the remote Zanskar, Lahaul and Spiti to the south, much of Ngari including the Rudok region and Guge in the east, Aksai Chin in the northeast (extending to the Kun Lun Mountains), and the Nubra Valley to the north over Khardong La in the Ladakh Range. Contemporary Ladakh borders Tibet to the east, the Lahaul and Spiti regions to the south, the Vale of Kashmir, Jammu and Baltiyul regions to the west, and the southwest corner of Xinjiang across the Karakoram Pass in the far north.Aksai Chin is one of the disputed border areas between China and India. It is administered by China as part of Hotan County but is also claimed by India as a part of the Ladakh region of the state of Jammu and Kashmir. In 1962, China and India fought a brief war over Aksai Chin and Arunachal Pradesh, but in 1993 and 1996 the two countries signed agreements to respect the Line of Actual Control. In the past Ladakh gained importance from its strategic location at the crossroads of important trade routes, but since the Chinese authorities closed the borders with Tibet and Central Asia in the 1960s, international trade has dwindled except for tourism. Since 1974, the Government of India has successfully encouraged tourism in Ladakh. Since Ladakh is a part of strategically important Jammu and Kashmir, the Indian military maintains a strong presence in the region.The largest town in Ladakh is Leh, followed by Kargil. Tibetan Buddhists (39.7%) and Hindus (12.1%) collectively represent the majority of the population while a plurality of Ladakhis (46.4%) are Muslims (mainly Shia). Other religious groups include Sikhs etc. Some Ladakhi activists have in recent times called for Ladakh to be constituted as a union territory because of perceived unfair treatment by Kashmir and Ladakh's cultural differences with predominantly Sunni Muslim Kashmir.Ladakh is the highest plateau in the state of Jammu & Kashmir with much of it being over 3,000 m (9,800 ft). It extends from the Himalayan to the Kunlun Ranges and includes the upper Indus River valley.Ladakhi food has much in common with Tibetan food, the most prominent foods being thukpa (noodle soup) and tsampa, known in Ladakhi as ngampe (roasted barley flour). Edible without cooking, tsampa makes useful trekking food.

Mongolia is a landlocked country in East Asia. Its area is roughly equivalent with the historical territory of Outer Mongolia, and that term is sometimes used to refer to the current state. It is sandwiched between China to the south and Russia to the north. Mongolia does not share a border with Kazakhstan, although only 37 kilometres (23 mi) separates them.At 1,564,116 square kilometres (603,909 sq mi), Mongolia is the 18th-largest and the most sparsely populated unitary sovereign statein the world, with a population of around 3 million people. It is also the world's second-largest landlocked country behind Kazakhstan and the largest landlocked country that does not border a closed sea. The country contains very little arable land, as much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to about 45% of the country's population. Ulaanbaatar also shares the rank of the world's coldest capital city with Moscow, Ottawa, and Astana. Approximately 30% of the population is nomadic or semi-nomadic; horse culture is still integral. The majority of its population are Buddhists. The non-religious population is the second largest group. Islam is the dominant religion among ethnic Kazakhs. The majority of the state's citizens are of Mongol ethnicity, although Kazakhs, Tuvans, and other minorities also live in the country, especially in the west. Mongolia joined the World Trade Organization in 1997 and seeks to expand its participation in regional economic and trade groups.The area of what is now Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the Turkic Khaganate, and others. In 1206, Genghis Khan founded the Mongol Empire, which became the largest contiguous land empire in history. His grandson Kublai Khan conquered China to establish the Yuan dynasty. After the collapse of the Yuan, the Mongols retreated to Mongolia and resumed their earlier pattern of factional conflict, except during the era of Dayan Khan and Tumen Zasagt Khan.In the 16th century, Tibetan Buddhism began to spread in Mongolia, being further led by the Manchu-founded Qing dynasty, which absorbed the country in the 17th century. By the early 1900s, almost one-third of the adult male population were Buddhist monks. After the collapse of the Qing dynasty in 1911, Mongolia declared independence, and achieved actual independence from the Republic of China in 1921. Shortly thereafter, the country came under the control of the Soviet Union, which had aided its independence from China. In 1924, the Mongolian People's Republic was founded as a socialist state. After the anti-Communist revolutions of 1989, Mongolia conducted its own peaceful democratic revolution in early 1990. This led to a multi-party system, a new constitution of 1992, and transition to a market economy.The population during the Copper Age has been described as mongoloid in the east of what is now Mongolia, and as europoid in the west Tocharians (Yuezhi) and Scythians inhabited western Mongolia during the Bronze Age. The mummy of a Scythian warrior, which is believed to be about 2,500 years old, was a 30- to 40-year-old man with blond hair; it was found in the Altai, Mongolia. As equine nomadism was introduced into Mongolia, the political center of the Eurasian Steppe also shifted to Mongolia, where it remained until the 18th century CE. The intrusions of northern pastoralists (e.g. the Guifang, Shanrong, and Donghu) into China during the Shang dynasty (1600-1046 BC) and Zhou dynasty (1046-256 BC) presaged the age of nomadic empires.

Derbyshire is a county in the East Midlands of England. A substantial portion of the Peak District National Park lies within Derbyshire, containing the southern extremity of the Pennine range of hills which extend into the north of the county. The county contains part of the National Forest, and borders on Greater Manchester to the northwest, West Yorkshire to the north, South Yorkshire to the northeast, Nottinghamshire to the east, Leicestershire to the southeast, Staffordshire to the west and southwest and Cheshire also to the west. Kinder Scout, at 636 metres (2,087 ft), is the highest point in the county, whilst Trent Meadows, where the River Trent leaves Derbyshire, is its lowest point at 27 metres (89 ft). The River Derwentis the county's longest river at 66 miles (106 km), and runs roughly north to south through the county. In 2003 the Ordnance Survey placed Church Flatts Farm at Coton in the Elms (near Swadlincote) as the furthest point from the sea in Great Britain.The city of Derby is a unitary authority area, but remains part of the ceremonial county of Derbyshire. The non-metropolitan county contains 30 towns with between 10,000 and 100,000 inhabitants. There is a large amount of sparsely populated agricultural upland: 75% of the population live in 25% of the area.The area that is now Derbyshire was first visited, probably briefly, by humans 200,000 years ago during the Aveley interglacialas evidenced by a Middle Paleolithic Acheulean hand axe found near Hopton. Further occupation came with the Upper Paleolithic and Neolithic periods of the Stone Age when Mesolithic hunter gatherers roamed the hilly tundra. Evidence of these nomadic tribes has been found in limestone caves located on the Nottinghamshire border. Deposits left in the caves date the occupancy at around 12,000 to 7,000 BCE.Because of its central location in England, and its altitude range from 27 metres in the south to 636 metres in the north, Derbyshire contains many species at the edge of their UK distribution ranges. Some species with a predominantly northern British distribution are at the southern limit of their range, whilst others with a more southern distribution are at their northern limit in Derbyshire. As climate change progresses, a number of sensitive species are now being seen to be either expanding or contracting their range as a result.A number of specialist organisations protect, promote and monitor records of individual animal groups across Derbyshire. The main ones are Derbyshire Ornithological Society; Derbyshire Mammal Group; Derbyshire Bat Group, Derbyshire Amphibian and Reptile Group, and the Derbyshire & Nottingham Entomological Society. All maintain databases of wildlife sightings, whilst some such as the Derbyshire Ornithological Society provide alerts of rare sightings on their websites or social media pages, and also publish major works describing the status and distribution of species.The county of Derbyshire has many attractions for both tourists and local people. The county offers Peak District scenery such as Mam Tor and Kinder Scout, and more metropolitan attractions such as Bakewell, Buxton and Derby. Local places of interest include Bolsover Castle, Castleton, Chatsworth House, National Tramway Museum at Crich, Peak Rail steam railway, Midland Railway steam railway, Dovedale, Haddon Hall, the Heights of Abraham and Matlock Bath.

Zermatt is a municipality in the district of Visp in the German-speaking section of the canton of Valais in Switzerland. It has a population of about 5,800 inhabitants and is classified as a town by the Swiss Federal Statistical Office (FSO).It lies at the upper end of Mattertal at an elevation of 1,620 m (5,310 ft), at the foot of Switzerland's highest peaks. It lies about 10 km (6.2 mi) from the over 10,800 ft (3,291.84 m) high Theodul Pass bordering Italy.Zermatt is famed as a mountaineering and ski resort of the Swiss Alps. Until the mid-19th century, it was predominantly an agricultural community; the first and tragic ascent of the Matterhorn in 1865 was followed by a rush on the mountains surrounding the village, leading to the construction of many tourist facilities. The year-round population (as of December 2017) is 5,643, though there may be several times as many tourists in Zermatt at any one time. Much of the local economy is based on tourism, with about half of the jobs in town in hotels or restaurants and just under half of all apartments are vacation apartments. Just over one-third of the permanent population was born in the town, while another third moved to Zermatt from outside Switzerland.The name of Zermatt, as well as that of the Matterhorn itself, derives from the alpine meadows, or matten (in German), in the valley. The town of Zermatt lies at the southern end of the Matter Valley (German: Mattertal), which is one of the lateral branches of the grand Valley of the Rhône. Zermatt is almost completely surrounded by the high mountains of the Pennine Alps including Monte Rosa (specifically its tallest peak, named Dufourspitze), Switzerland's highest peak at 4,634 metres (15,203 ft) above sea level.Zermatt is traversed by the main river of the valley: the Matter Vispa, which rises at the glaciers at the feet of the highest peaks: the Gorner Glacier on the east side near Monte Rosa and the Zmutt Glacier on the west side between Dent d'Hérens and Dent Blanche.To prevent air pollution, which could obscure the town's view of the Matterhorn, the entire town is a combustion-engine car-free zone. Almost all vehicles in Zermatt are battery driven and almost completely silent. Electric vehicles are allowed for local commerces. The Cantonal police can issue a permit which allows residents to drive and park at the northern outskirts and for the permission to be bring combustion engine vehicles in to the town such as construction vehicles. Emergency and municipal vehicles, (fire trucks, ambulances, police etc.) generally use combustion engines, although even some of these are non-combustion, (garbage trucks, etc.).

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle. Therefore, on Earth, volcanoes are generally found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-oceanic ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, e.g., in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande Rift in North America. This type of volcanism falls under the umbrella of "plate hypothesis" volcanism. Volcanism away from plate boundaries has also been explained as mantle plumes. These so-called "hotspots", for example Hawaii, are postulated to arise from upwelling diapirs with magma from the core-mantle boundary, 3,000 km deep in the Earth. Volcanoes are usually not created where two tectonic plates slide past one another.Erupting volcanoes can pose many hazards, not only in the immediate vicinity of the eruption. One such hazard is that volcanic ash can be a threat to aircraft, in particular those with jet engines where ash particles can be melted by the high operating temperature; the melted particles then adhere to the turbine blades and alter their shape, disrupting the operation of the turbine. Large eruptions can affect temperature as ash and droplets of sulfuric acid obscure the sun and cool the Earth's lower atmosphere (or troposphere); however, they also absorb heat radiated from the Earth, thereby warming the upper atmosphere (or stratosphere). Historically, volcanic winters have caused catastrophic famines.A volcanic winter is thought to have taken place around 70,000 years ago after the supereruption of Lake Toba on Sumatra island in Indonesia. According to the Toba catastrophe theory to which some anthropologists and archeologists subscribe, it had global consequences, killing most humans then alive and creating a population bottleneck that affected the genetic inheritance of all humans today. It has been suggested that volcanic activity caused or contributed to the End-Ordovician, Permian-Triassic, Late Devonian mass extinctions, and possibly others. The massive eruptive event which formed the Siberian Traps, one of the largest known volcanic events of the last 500 million years of Earth's geological history, continued for a million years and is considered to be the likely cause of the "Great Dying" about 250 million years ago, which is estimated to have killed 90% of species existing at the time.

Strasbourg is the capital and largest city of the Grand Est region of France and is the official seat of the European Parliament. Located at the border with Germany in the historic region of Alsace, it is the capital of the Bas-Rhin department. In 2016, the city proper had 279,284 inhabitants and both the Eurométropole de Strasbourg (Greater Strasbourg) and the Arrondissement of Strasbourg had 491,409 inhabitants. Strasbourg's metropolitan area had a population of 785,839 in 2015 (not counting the section across the border in Germany), making it the ninth largest metro area in France and home to 13% of the Grand Est region's inhabitants. The transnational Eurodistrict Strasbourg-Ortenau had a population of 915,000 inhabitants in 2014. Strasbourg is one of the de facto capitals of the European Union (alongside Brussels and Luxembourg), as it is the seat of several European institutions, such as the Council of Europe (with its European Court of Human Rights, its European Directorate for the Quality of Medicines and its European Audiovisual Observatory) and the Eurocorps, as well as the European Parliament and the European Ombudsman of the European Union. The city is also the seat of the Central Commission for Navigation on the Rhine and the International Institute of Human Rights. Strasbourg's historic city centre, the Grande Île (Grand Island), was classified a World Heritage Site by UNESCO in 1988, the first time such an honour was placed on an entire city centre. Strasbourg is immersed in Franco-German culture and although violently disputed throughout history, has been a cultural bridge between France and Germany for centuries, especially through the University of Strasbourg, currently the second largest in France, and the coexistence of Catholic and Protestant culture. It is also home to the largest Islamic place of worship in France, the Strasbourg Grand Mosque. Economically, Strasbourg is an important centre of manufacturing and engineering, as well as a hub of road, rail, and river transportation. The port of Strasbourg is the second largest on the Rhine after Duisburg, Germany. In spite of its position far inland, Strasbourg's climate is classified as oceanic (Köppen climate classification Cfb), with warm, relatively sunny summers and cool, overcast winters. Precipitation is elevated from mid-spring to the end of summer, but remains largely constant throughout the year, totaling 631.4 mm (24.9 in) annually. On average, snow falls 30 days per year.Strasbourg's location in the Rhine valley, sheltered from the dominant winds by the Vosges and Black Forest mountains, results in poor natural ventilation, making Strasbourg one of the most atmospherically polluted cities of France.The largest square at the centre of the city of Strasbourg is the Place Kléber. For a city of comparatively small size, Strasbourg displays a large quantity and variety of museums.

Black sand is sand that is black in color. One type of black sand is a heavy, glossy, partly magnetic mixture of usually fine sands, found as part of a placer deposit. Another type of black sand, found on beaches near a volcano, consists of tiny fragments of Basalt.While some beaches are predominantly made of black sand, even other color beaches (e.g. gold and white) can often have deposits of black sand, particularly after storms. Larger waves can sort out sand grains leaving deposits of heavy minerals visible on the surface of erosion scarps.Black sands are used by miners and prospectors to indicate the presence of a placer formation. Placer mining activities produce a concentrate that is composed mostly of black sand. Black sand concentrates often contain additional valuables, other than precious metals: rare earth elements, thorium, titanium, tungsten, zirconium and others are often fractionated during igneous processes into a common mineral-suite that becomes black sands after weathering and erosion.Several gemstones, such as garnet, topaz, ruby, sapphire, and diamond are found in placers and in the course of placer mining, and sands of these gems are found in black sands and concentrates. Purple or ruby-colored garnet sand often forms a showy surface dressing on ocean beach placers.An example of a non-volcanic black sand beach is at Langkawi in Malaysia.When lava contacts water, it cools rapidly and shatters into sand and fragmented debris of various size. Much of the debris is small enough to be considered sand. A large lava flow entering an ocean may produce enough basalt fragments to build a new black sand beach almost overnight. The famous "black sand" beaches of Hawaii, such as Punaluʻu Beach and Kehena Beach, were created virtually instantaneously by the violent interaction between hot lava and sea water. Since a black sand beach is made by a lava flow in a one time event, they tend to be rather short lived since sands do not get replenished if currents or storms wash sand into deeper water. For this reason, the state of Hawaii has made it illegal to remove black sand from its beaches. Further, a black sand beach is vulnerable to being inundated by future lava flows, as was the case for Hawaiʻi's Kaimū, usually known simply as Black Sand Beach, and Kalapana beaches.[3] An even shorter-lived black sand beach was Kamoamoa.[4] Unlike with white and green sand beaches, walking barefoot on black sand can result in burns, as the black sand absorbs a greater fraction of the solar radiation falling upon it.When lava contacts water, it cools rapidly and shatters into sand and fragmented debris of various size.

Iguazú Falls or Iguaçu Falls are waterfalls of the Iguazu River on the border of the Argentine provinceof Misiones and the Brazilian state of Paraná. Together, they make up the largest waterfall system in the world. The falls divide the river into the upper and lower Iguazu. The Iguazu River rises near the heart of the city of Curitiba. For most of its course, the river flows through Brazil; however, most of the falls are on the Argentine side. Below its confluence with the San Antonio River, the Iguazu River forms the boundary between Argentina and Brazil.The name "Iguazú" comes from the Guarani or Tupi words "y" [ɨ], meaning "water," and "ûasú "[waˈsu], meaning "big." Legend has it that a deity planned to marry a beautiful woman named Naipí, who fled with her mortal lover Tarobá in a canoe. In a rage, the deity sliced the river, creating the waterfalls and condemning the lovers to an eternal fall. The first European to record the existence of the falls was the Spanish Conquistador Álvar Núñez Cabeza de Vaca in 1541.The staircase character of the falls consists of a two-step waterfall formed by three layers of basalt. The steps are 35 and 40 m in height. The columnar basalt rock sequences are part of the 1000 m thick Serra Geral Formation within the Paleozoic-Mesozoic Paraná Basin. The tops of these sequences are characterized by 8-10 m of highly resistant vesicular basalt and the contact between these layers controls the shape of the falls. Headwater erosion rates are estimated at 1.4-2.1 cm/year. The Iguazu Falls are located where the Iguazu River tumbles over the edge of the Paraná Plateau, 23 kilometres (14 mi) upriver from the Iguazu's confluence with the Paraná River.The Iguazu Falls are arranged in a way that resembles a reversed letter "J." The Argentina-Brazil border runs through the Devil's Throat. On the right bank is the Brazilian territory, which is home to more than 95% of the Iguazu River basin but has just over 20% of the jumps of these falls, and the left side jumps are Argentine, which makes up almost 80% of the falls.Two international airports are close to Iguazú Falls: the Argentine Cataratas del Iguazú International Airport (IGR) and the Brazilian Foz do Iguaçu International Airport (IGU). Bus and taxi services are available from and to the Airport-Falls. Aerolíneas Argentinasand LATAM Argentina[5] have direct flights from Buenos Aires to Iguazu International Airport Krause. Azul, GOL, and LATAM Brasil offer services from main Brazilian cities to Foz do Iguaçu.The Iguazu Falls experience a humid subtropical climate (Cfa, according to the Köppen climate classification) with abundant precipitation and high temperatures year-round.

Vikings were Norse seafarers, mainly speaking the Old Norse language, who during the late 8th to late 11th centuries, raided and traded from their Northern European homelands across wide areas of Europe, and explored westwards to Iceland, Greenland, and Vinland. The term is also commonly extended in modern English and other vernaculars to the inhabitants of Norse home communities during what has become known as the Viking Age. This period of Nordic military, mercantile and demographic expansion constitutes an important element in the early medieval history of Scandinavia, Estonia, the British Isles, France, Kievan Rus' and Sicily. Facilitated by advanced sailing and navigational skills, and characterised by the longship, Viking activities at times also extended into the Mediterranean littoral, North Africa, the Middle East and Central Asia. Following extended phases of (primarily sea- or river-borne) exploration, expansion and settlement, Viking (Norse) communities and governments were established in diverse areas of north-western Europe, Belarus, Ukraine and European Russia, the North Atlantic islands and as far as the north-eastern coast of North America. This period of expansion witnessed the wider dissemination of Norse culture, while simultaneously introducing strong foreign cultural influences into Scandinavia itself, with profound developmental implications in both directions.Popular, modern conceptions of the Vikings-the term frequently applied casually to their modern descendants and the inhabitants of modern Scandinavia-often strongly differ from the complex picture that emerges from archaeology and historical sources. A romanticised picture of Vikings as noble savages began to emerge in the 18th century; this developed and became widely propagated during the 19th-century Viking revival. Perceived views of the Vikings as alternatively violent, piratical heathens or as intrepid adventurers owe much to conflicting varieties of the modern Viking myth that had taken shape by the early 20th century. Current popular representations of the Vikings are typically based on cultural clichés and stereotypes, complicating modern appreciation of the Viking legacy. These representations are not always accurate-for example, there is no evidence that they wore horned helmets.The Vikings were known as Ascomanni ("ashmen") by the Germans for the ash wood of their boats, Dubgail and Finngail ( "dark and fair foreigners") by the Irish, Lochlannach ("lake person") by the Gaels and Dene (Dane) by the Anglo-Saxons. The period from the earliest recorded raids in the 790s until the Norman conquest of England in 1066 is commonly known as the Viking Age of Scandinavian history.Thus the end of the Viking Age for the Scandinavians also marks the start of their relatively brief Middle Ages.Colonization of Iceland by Norwegian Vikings began in the ninth century. During the Viking Age, Scandinavian men and women travelled to many parts of Europe and beyond, in a cultural diaspora that left its traces from Newfoundland to Byzantium.A variety of sources illuminate the culture, activities, and beliefs of the Vikings. Although they were generally a non-literate culture that produced no literary legacy, they had an alphabet and described themselves and their world on runestones. The most important primary sources on the Vikings are contemporary texts from Scandinavia and regions where the Vikings were active.[79]Writing in Latin letters was introduced to Scandinavia with Christianity, so there are few native documentary sources from Scandinavia before the late 11th and early 12th centuries.

Sikhism is an Indian religion that originated in the Punjab region in the northern part of the Indian subcontinent around the end of the 15th century, and has variously been defined as monotheistic, monistic and panentheistic. It is one of the youngest of the major world religions, and the world's fifth-largest organized religion, as well as being the world's ninth-largest overall religion. The fundamental beliefs of Sikhism, articulated in the sacred scripture Guru Granth Sahib, include faith and meditation on the name of the one creator, divine unity and equality of all humankind, engaging in selfless service, striving for justice for the benefit and prosperity of all, and honest conduct and livelihood while living a householder's life. In the early 21st century there were nearly 25 million Sikhs worldwide, the great majority of them living in Punjab, according to the Encyclopaedia Britannica. Sikhism is based on the spiritual teachings of Guru Nanak, the first Guru (1469-1539), ] and the nine Sikh gurus that succeeded him. The Tenth Guru, Guru Gobind Singh, named the Sikh scripture Guru Granth Sahib as his successor, terminating the line of human Gurus and making the scripture the eternal, religious spiritual guide for Sikhs. The Sikh scripture opens with Ik Onkar (ੴ), its Mul Mantar and fundamental prayer about One Supreme Being (God). Sikhism emphasizes simran (meditation on the words of the Guru Granth Sahib), that can be expressed musically through kirtan or internally through Nam Japo (repeat God's name) as a means to feel God's presence. It teaches followers to transform the "Five Thieves" (lust, rage, greed, attachment, and ego). Hand in hand, secular life is considered to be intertwined with the spiritual life. Guru Nanak taught that living an "active, creative, and practical life" of "truthfulness, fidelity, self-control and purity" is above the metaphysical truth, and that the ideal man is one who "establishes union with God, knows His Will, and carries out that Will" Guru Hargobind, the sixth Sikh Guru, established the political/temporal (Miri) and spiritual (Piri) realms to be mutually coexistent. Sikhism evolved in times of religious persecution. Two of the Sikh gurus - Guru Arjan (1563-1605) and Guru Tegh Bahadur (1621-1675) - were tortured and executed by the Mughal rulers after they refused to convert to Islam. The persecution of Sikhs triggered the founding of the Khalsa as an order to protect the freedom of conscience and religion, with qualities of a "Sant-Sipāhī" - a saint-soldier. The Khalsa was founded by the last Sikh Guru, Guru Gobind Singh.The majority of Sikh scriptures were originally written in the Gurmukhī alphabet, a script standardised by Guru Angad out of Laṇḍā scripts used in North India. Adherents of Sikhism are known as Sikhs, which means students or disciples of the Guru. The anglicised word 'Sikhism' is derived from the Punjabi verb Sikhi, with roots in Sikhana (to learn), and Sikhi connotes the "temporal path of learning".God in Sikhism is known as Ik Onkar, the One Supreme Reality or the all-pervading spirit (which is taken to mean God). This spirit has no gender in Sikhism, though translations may present it as masculine. It is also Akaal Purkh (beyond time and space) and Nirankar (without form). In addition, Nanak wrote that there are many worlds on which it has created life.The traditional Mul Mantar goes from Ik Oankar until Nanak Hosee Bhee Sach. The opening line of the Guru Granth Sahib and each subsequent raga, mentions Ik Oankar Vaisakhi which includes Parades and Nagar Kirtan occurs on 13 April or 14 April.Nagar Kirtan involves the processional singing of holy hymns throughout a community.Band Chor Diwas has been another important Sikh festival in its history.Hola Mohalla is a tradition started by Guru Gobind Singh.Gurpurbs are celebrations or commemorations based on the lives of the Sikh gurus.

Saint Petersburg is Russia's second-largest city after Moscow, with 5 million inhabitants in 2012, part of the Saint Petersburg agglomeration with a population of 6.2 million (2015). An important Russian port on the Baltic Sea, it has a status of a federal subject (a federal city). Situated on the Neva River, at the head of the Gulf of Finland on the Baltic Sea, it was founded by Tsar Peter the Great on May 27 [O.S. 16] 1703. On 1 September 1914, the name was changed from Saint Petersburg to Petrograd (Russian: Петрогра́д, IPA: [pʲɪtrɐˈgrat]), on 26 January 1924 to Leningrad (Russian: Ленингра́д, IPA: [lʲɪnʲɪnˈgrat]), and on 7 September 1991 back to Saint Petersburg. Between 1713 and 1728 and in 1732-1918, Saint Petersburg was the capital of Imperial Russia. In 1918, the central government bodies moved to Moscow. Saint Petersburg is one of the modern cities of Russia, as well as its cultural capital. The Historic Centre of Saint Petersburg and Related Groups of Monuments constitute a UNESCO World Heritage Site. Saint Petersburg is home to the Hermitage, one of the largest art museums in the world. Many foreign consulates, international corporations, banks and businesses have offices in Saint Petersburg. Although the central part of the city has a UNESCO designation (there are about 8,000 architectural monuments in Petersburg), the preservation of its historical and architectural environment became controversial. After 2005, the demolition of older buildings in the historical centre was permitted. In 2006 Gazprom announced an ambitious project to erect a 396-meter skyscraper opposite to Smolny, which[ could result in the loss of the unique line of Petersburg landscape. Urgent protests by citizens and prominent public figures of Russia against this project were not considered by Governor Valentina Matviyenko and the city authorities until December 2010, when after the statement of President Dmitry Medvedev, the city decided to find a more appropriate location for this project. In the same year, the new location for the project was relocated to Lakhta, a historical area northwest of the center city, and the new project would be named Lakhta Center. Construction was approved by Gazprom and the city administration and commenced in 2012. The Lakhta Center would be the first tallest skyscraper in Russia and Europe that is outside of Moscow.

Java (Indonesian: is an island of Indonesia, bordered by the Indian Ocean on the south and the Java Sea on the north. With a population of over 141 million (Java only) or 145 million (including the inhabitants of its surrounding islands), Java is the home to 56.7 percent of the Indonesian population and is the world's most populous island. The Indonesian capital city, Jakarta, is located on its northwestern coast. Much of Indonesian history took place on Java. It was the center of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally. Four of Indonesia's eight UNESCO world heritage sites are located in Java: Ujung Kulon National Park, Borobudur Temple, Prambanan Temple, and Sangiran Early Man Site.Formed mostly as the result of volcanic eruptions from geologic subduction between Sunda Plate and Australian Plate, Java is the 13th largest island in the world and the fifth largest in Indonesia by landmass at about 138,800 square kilometres (53,600 sq mi). A chain of volcanic mountains forms an east-west spine along the island. Three main languages are spoken on the island: Javanese, Sundanese, and Madurese, where Javanese is the most spoken; it is the native language of about 60 million Javanese people in Indonesia, most of whom live on Java. Furthermore, most residents are bilingual, speaking Indonesian (the official language of Indonesia) as their first or second language. Java is divided into four administrative provinces, West Java, Central Java, East Java, and Banten, and two special regions, Jakarta and Yogyakarta.The natural environment of Java is tropical rainforest, with ecosystems ranging from coastal mangrove forests on the north coast, rocky coastal cliffs on the southern coast, and low-lying tropical forests to high altitude rainforests on the slopes of mountainous volcanic regions in the interior.However, the first major principality was the Medang Kingdom that was founded in central Java at the beginning of the 8th century. Medang's religion centred on the Hindu god Shiva, and the kingdom produced some of Java's earliest Hindu temples on the Dieng Plateau. Around the 8th century the Sailendra dynasty rose in Kedu Plain and become the patron of Mahayana Buddhism. This ancient kingdom built monuments such as the 9th century Borobudur and Prambanan in central Java.Around the 10th century the centre of power shifted from central to eastern Java. The eastern Javanese kingdoms of Kediri, Singhasari and Majapahit were mainly dependent on rice agriculture, yet also pursued trade within the Indonesian archipelago, and with China and India.Islam became the dominant religion in Java at the end of the 16th century.Java's contact with the European colonial powers began in 1522 with a treaty between the Sunda kingdom and the Portuguese in Malacca. In 1811, Java was captured by the British, becoming a possession of the British Empire, and Sir Stamford Raffles was appointed as the island's Governor. In 1814, Java was returned to the Dutch under the terms of the Treaty of Paris.Indonesian nationalism first took hold in Java in the early 20th century, and the struggle to secure the country's independence following World War II was centered in Java. In 1949, Indonesia became independent and the island has dominated Indonesian social, political and economic life, which has been the source of resentment of those residents in other islands.

Love encompasses a variety of strong and positive emotional and mental states, ranging from the most sublime virtue or good habit, the deepest interpersonal affection and to the simplest pleasure. An example of this range of meanings is that the love of a mother differs from the love of a spouse, which differs from the love of food. Most commonly, love refers to a feeling of strong attraction and emotional attachment. Love can also be a virtue representing human kindness, compassion, and affection, as "the unselfish loyal and benevolent concern for the good of another." It may also describe compassionate and affectionate actions towards other humans, one's self or animals. Love in its various forms acts as a major facilitator of interpersonal relationships and, owing to its central psychological importance, is one of the most common themes in the creative arts. Love has been postulated to be a function to keep human beings together against menaces and to facilitate the continuation of the species. Ancient Greek philosophers identified five forms of love: essentially, familial love (in Greek, Storge), friendly love or platonic love(Philia), romantic love (Eros), guest love (Xenia) and divine love (Agape). Modern authors have distinguished further varieties of love: unrequited love, infatuated love, self-love, and courtly love. Asian cultures have also distinguished Ren, Kama, Bhakti, Mettā, Ishq, Chesed, and other variants or symbioses of these states. Love has additional religious or spiritual meaning. This diversity of uses and meanings combined with the complexity of the feelings involved makes love unusually difficult to consistently define, compared to other emotional states.Greek distinguishes several different senses in which the word "love" is used. Ancient Greeks identified four forms of love: kinship or familiarity (in Greek, storge), friendship and/or platonic desire (philia), sexual and/or romantic desire (eros), and self-emptying or divine love (agape). Modern authors have distinguished further varieties of romantic love. However, with Greek (as with many other languages), it has been historically difficult to separate the meanings of these words totally.Two philosophical underpinnings of love exist in the Chinese tradition, one from Confucianism which emphasized actions and duty while the other came from Mohism which championed a universal love.In Mandarin Chinese, 愛 (ài) is often used as the equivalent of the Western concept of love. 愛 (ài) is used as both a verb (e.g. 我愛你, Wǒ ài nǐ, or "I love you") and a noun (such as 愛情 àiqíng, or "romantic love"). Instead of frequently saying "I love you" as in some Western societies, the Chinese are more likely to express feelings of affection in a more casual way. Consequently, "I like you" (我喜欢你, Wǒ xǐhuan nǐ) is a more common way of expressing affection in Chinese; it is more playful and less serious.[36] This is also true in Japanese (suki da, 好きだ).Kama in Indian literature means "desire, wish or longing." In contemporary literature, kama refers usually to sexual desire. However, the term also refers to any sensory enjoyment, emotional attraction and aesthetic pleasure such as from arts, dance, music, painting, sculpture and nature.Rumi, Hafiz and Sa'di are icons of the passion and love that the Persian culture and language present. The Persian word for love is Ishq, which is derived from Arabic language, however it is considered by most to be too stalwart a term for interpersonal love and is more commonly substituted for "doost dashtan" ("liking"). In the Persian culture, everything is encompassed by love and all is for love, starting from loving friends and family, husbands and wives, and eventually reaching the divine love that is the ultimate goal in life.

Baroque architecture is the building style of the Baroque era, begun in late 16th-century Italy, that took the Roman vocabulary of Renaissance architecture and used it in a new rhetorical and theatrical fashion, often to express the triumph of the Catholic Church. It was characterized by new explorations of form, light and shadow, and dramatic intensity. Common features of Baroque architecture included gigantism of proportions; a large open central space where everyone could see the altar; twisting columns, theatrical effects, including light coming from a cupola above; dramatic interior effects created with bronze and gilding; clusters of sculpted angels and other figures high overhead; and an extensive use of trompe-l'oeil, also called "quadratura," with painted architectural details and figures on the walls and ceiling, to increase the dramatic and theatrical effect. Whereas the Renaissance drew on the wealth and power of the Italian courts and was a blend of secular and religious forces, the Baroque was, initially at least, directly linked to the Counter-Reformation, a movement within the Catholic Church to reform itself in response to the Protestant Reformation. Baroque architecture and its embellishments were on the one hand more accessible to the emotions and on the other hand, a visible statement of the wealth and power of the Catholic Church. The new style manifested itself in particular in the context of the new religious orders, like the Theatines and the Jesuits who aimed to improve popular piety.Lutheran Baroque art, such as the example of Dresden Frauenkirche (1726-1743), developed as a confessional marker of identity, in response to the Great Iconoclasm of Calvinists. The architecture of the High Roman Baroque can be assigned to the papal reigns of Urban VIII, Innocent X and Alexander VII, spanning from 1623 to 1667. The three principal architects of this period were the sculptor Gianlorenzo Bernini, Francesco Borromini and the painter Pietro da Cortona and each evolved his own distinctively individual architectural expression.Dissemination of Baroque architecture to the south of Italy resulted in regional variations such as Sicilian Baroque architecture or that of Naples and Lecce. To the north, the Theatine architect Camillo-Guarino Guarini, Bernardo Vittone and Sicilian born Filippo Juvarra contributed Baroque buildings to the city of Turin and the Piedmont region.A synthesis of Bernini, Borromini, and Cortona's architecture can be seen in the late Baroque architecture of northern Europe, which paved the way for the more decorative Rococo style.By the middle of the 17th century, the Baroque style had found its secular expression in the form of grand palaces, first in France-with the Château de Maisons (1642) near Paris by François Mansart-and then throughout Europe.During the 17th century, Baroque architecture spread through Europe and Latin America, where it was particularly promoted by the Jesuits.

Lebanon is a country in Western Asia. It is bordered by Syria to the north and east and Israel to the south, while Cyprus is west across the Mediterranean Sea. Lebanon's location at the crossroads of the Mediterranean Basin and the Arabian hinterland facilitated its rich history and shaped a cultural identity of religious and ethnic diversity. At just 10,452 km2 (4,036 sq. mi.), it is the smallest recognized sovereign state on the mainland Asian continent. The earliest evidence of civilization in Lebanon dates back more than seven thousand years, predating recorded history. Lebanon was the home of the Canaanites/Phoenicians and their kingdoms, a maritime culture that flourished for over a thousand years (c. 1550-539 BC). In 64 BC, the region came under the rule of the Roman Empire, and eventually became one of the Empire's leading centers of Christianity. In the Mount Lebanon range a monastic tradition known as the Maronite Church was established. As the Arab Muslims conquered the region, the Maronites held onto their religion and identity. However, a new religious group, the Druze, established themselves in Mount Lebanon as well, generating a religious divide that has lasted for centuries. During the Crusades, the Maronites re-established contact with the Roman Catholic Church and asserted their communion with Rome. The ties they established with the Latins have influenced the region into the modern era.The region eventually was ruled by the Ottoman Empire from 1516 to 1918. Following the collapse of the empire after World War I, the five provinces that constitute modern Lebanon came under the French Mandate of Lebanon. The French expanded the borders of the Mount Lebanon Governorate, which was mostly populated by Maronites and Druze, to include more Muslims. Lebanon gained independence in 1943, establishing confessionalism, a unique, Consociationalism-type of political system with a power-sharing mechanism based on religious communities. Bechara El Khoury, President of Lebanon during the independence, Riad El-Solh, first Lebanese prime minister and Emir Majid Arslan II, first Lebanese minister of defence, are considered the founders of the modern Republic of Lebanon and are national heroes for having led the country's independence. Foreign troops withdrew completely from Lebanon on 31 December 1946. Lebanon has been a member of the United Nations since its founding in 1945 as well as of the Arab League (1945), the Non-Aligned Movement (1961), Organisation of the Islamic Cooperation (1969) and the Organisation internationale de la francophonie (1973).Despite its small size, the country has developed a well-known culture and has been highly influential in the Arab world, powered by its large diaspora. Before the Lebanese Civil War (1975-1990), the country experienced a period of relative calm and renowned prosperity, driven by tourism, agriculture, commerce, and banking. Because of its financial power and diversity in its heyday, Lebanon was referred to as the "Switzerland of the East" during the 1960s, [ and its capital, Beirut, attracted so many tourists that it was known as "the Paris of the Middle East." At the end of the war, there were extensive efforts to revive the economy and rebuild national infrastructure. In spite of these troubles, Lebanon has the 7th highest Human Development Index and GDP per capita in the Arab world after the oil-rich economies of the Persian Gulf.

Yosemite National Park is an American national park located in the western Sierra Nevada of Central California, bounded on the southeast by Sierra National Forest and on the northwest by Stanislaus National Forest. The park, which is managed by the National Park Service, covers an area of 747,956 acres (1,168.681 sq mi; 302,687 ha; 3,026.87 km2) and sits in four counties: centered in Tuolumne and Mariposa, extending north and east to Mono and south to Madera County. Designated a World Heritage site in 1984, Yosemite is internationally recognized for its granite cliffs, waterfalls, clear streams, giant sequoia groves, lakes, mountains, meadows, glaciers, and biological diversity. Almost 95% of the park is designated wilderness. On average, about 4 million people visit Yosemite each year, and most spend the majority of their time in the 5.9 square miles (15 km2) of Yosemite Valley. The park set a visitation record in 2016, surpassing 5 million visitors for the first time in its history. Yosemite was central to the development of the national park idea. Galen Clark and others lobbied to protect Yosemite Valley from development, ultimately leading to President Abraham Lincoln's signing the Yosemite Grant in 1864. John Muir led a successful movement to have Congress establish a larger national park by 1890, one which encompassed the valley and its surrounding mountains and forests, paving the way for the National Park System. Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada, and the park supports a diversity of plants and animals. The park has an elevation range from 2,127 to 13,114 feet (648 to 3,997 m) and contains five major vegetation zones: chaparral and oak woodland, lower montane forest, upper montane forest, subalpine zone, and alpine. Of California's 7,000 plant species, about 50% occur in the Sierra Nevada and more than 20% are within Yosemite. The park contains suitable habitat for more than 160 rare plants, with rare local geologic formations and unique soils characterizing the restricted ranges many of these plants occupy.The geology of the Yosemite area is characterized by granitic rocks and remnants of older rock. About 10 million years ago, the Sierra Nevada was uplifted and then tilted to form its relatively gentle western slopes and the more dramatic eastern slopes. The uplift increased the steepness of stream and river beds, resulting in the formation of deep, narrow canyons. About one million years ago, snow and ice accumulated, forming glaciers at the higher alpine meadows that moved down the river valleys. Ice thickness in Yosemite Valley may have reached 4,000 feet (1,200 m) during the early glacial episode. The downslope movement of the ice masses cut and sculpted the U-shaped valley that attracts so many visitors to its scenic vistas today. The name "Yosemite" (meaning "killer" in Miwok) originally referred to the name of a renegade tribe which was driven out of the area (and possibly annihilated) by the Mariposa Battalion. Previously, the area had been called "Ahwahnee" ("big mouth") by indigenous people.

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.. Therefore, on Earth, volcanoes are generally found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-oceanic ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, e.g., in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande Rift in North America. This type of volcanism falls under the umbrella of "plate hypothesis" volcanism. Volcanism away from plate boundaries has also been explained as mantle plumes. These so-called "hotspots", for example Hawaii, are postulated to arise from upwelling diapirs with magma from the core-mantle boundary, 3,000 km deep in the Earth. Volcanoes are usually not created where two tectonic plates slide past one another. Erupting volcanoes can pose many hazards, not only in the immediate vicinity of the eruption. One such hazard is that volcanic ash can be a threat to aircraft, in particular those with jet engines where ash particles can be melted by the high operating temperature; the melted particles then adhere to the turbine blades and alter their shape, disrupting the operation of the turbine. Large eruptions can affect temperature as ash and droplets of sulfuric acid obscure the sun and cool the Earth's lower atmosphere (or troposphere); however, they also absorb heat radiated from the Earth, thereby warming the upper atmosphere (or stratosphere). Historically, volcanic winters have caused catastrophic famines. The word volcano is derived from the name of Vulcano, a volcanic island in the Aeolian Islands of Italy whose name in turn comes from Vulcan, the god of fire in Roman mythology. The study of volcanoes is called volcanology. Hotspots are volcanic areas believed to be formed by mantle plumes, which are hypothesized to be columns of hot material rising from the core-mantle boundary in a fixed space that causes large-volume melting. Because tectonic plates move across them, each volcano becomes dormant and is eventually re-formed as the plate advances over the postulated plume. The Hawaiian Islands are said to have been formed in such a manner; so has the Snake River Plain, with the Yellowstone Caldera being the part of the North American plate above the hot spot. This theory, however, has been doubted. The features of volcanoes are much more complicated and their structure and behavior depends on a number of factors. Shield volcanoes, so named for their broad, shield-like profiles, are formed by the eruption of low-viscosity lava that can flow a great distance from a vent. They generally do not explode catastrophically. Since low-viscosity magma is typically low in silica, shield volcanoes are more common in oceanic than continental settings. The Hawaiian volcanic chain is a series of shield cones, and they are common in Iceland, as well.

The unicorn is a legendary creature that has been described since antiquity as a beast with a single large, pointed, spiraling hornprojecting from its forehead. The unicorn was depicted in ancient seals of the Indus Valley Civilization and was mentioned by the ancient Greeks in accounts of natural history by various writers, including Ctesias, Strabo, Pliny the Younger, and Aelian. The Biblealso describes an animal, the re'em, which some versions translate as unicorn. In European folklore, the unicorn is often depicted as a white horse-like or goat-like animal with a long horn and cloven hooves (sometimes a goat's beard). In the Middle Ages and Renaissance, it was commonly described as an extremely wild woodland creature, a symbol of purity and grace, which could be captured only by a virgin. In the encyclopedias, its horn was said to have the power to render poisoned water potable and to heal sickness. In medieval and Renaissance times, the tusk of the narwhal was sometimes sold as unicorn horn.The horn itself and the substance it was made of was called alicorn, and it was believed that the horn holds magical and medicinal properties.One traditional method of hunting unicorns involved entrapment by a virgin.In one of his notebooks Leonardo da Vinci wrote: The unicorn, through its intemperance and not knowing how to control itself, for the love it bears to fair maidens forgets its ferocity and wildness; and laying aside all fear it will go up to a seated damsel and go to sleep in her lap, and thus the hunters take it.The famous late Gothic series of seven tapestry hangings The Hunt of the Unicorn are a high point in European tapestry manufacture, combining both secular and religious themes. The tapestries now hang in the Cloisters division of the Metropolitan Museum of Art in New York City. In heraldry the unicorn is best known as the symbol of Scotland.Golden coins known as the unicorn and half-unicorn, both with a unicorn on the obverse, were used in Scotland in the 15th and 16th century. In the same realm, carved unicorns were often used as finials on the pillars of Mercat crosses, and denoted that the settlement was a royal burgh. Certain noblemen such as the Earl of Kinnoull were given special permission to use the unicorn in their arms, as an augmentation of honour. The crest for Clan Cunningham bears a unicorn head

A yawn is a reflex consisting of the simultaneous inhalation of air and the stretching of the eardrums, followed by an exhalation of breath.Yawning (oscitation) most often occurs in adults immediately before and after sleep, during tedious activities and as a result of its contagious quality. It is commonly associated with tiredness, stress, sleepiness, or even boredom and hunger. In humans, yawning is often triggered by others yawning (e.g. seeing a person yawning, talking to someone on the phone who is yawning) and is a typical example of positive feedback. This "contagious" yawning has also been observed in chimpanzees, dogs, cats, birds, and reptiles, and can occur across species. Approximately 20 psychological reasons for yawning have been proposed by scholars, but there is little agreement on the primacy of any one. During a yawn, the tensor tympani muscle in the middle ear contracts, creating a rumbling noise from within the head. Yawning is sometimes accompanied, in humans and animals, by an instinctive act of stretching several parts of the body, including arms, neck, shoulders and back.In animals, yawning can serve as a warning signal. For example, Charles Darwin, in his book The Expression of the Emotions in Man and Animals, mentioned that baboons yawn to threaten their enemies, possibly by displaying large canine teeth. Similarly, Siamese fighting fish yawn only when they see a conspecific (same species) or their own mirror-image, and their yawn often accompanies aggressive attack. Guinea pigs also yawn in a display of dominance or anger, displaying their impressive incisor teeth. This is often accompanied by teeth chattering, purring and scent marking. Adelie penguins employ yawning as part of their courtship ritual. Penguin couples face off and the males engage in what is described as an "ecstatic display", opening their beaks and pointing their faces skyward. This trait has also been seen among emperor penguins. Researchers have been attempting to discover why these two different species share this trait, despite not sharing a habitat. Snakes yawn, both to realign their jaws after a meal and for respiratory reasons, as their trachea can be seen to expand when they do this. Dogs, and occasionally cats, often yawn after seeing people yawn and when they feel uncertain. Dogs demonstrate contagious yawning when exposed to human yawning. Dogs are very adept at reading human communication actions, so it is unclear if this phenomenon is rooted in evolutionary history or a result of domestication. Fish can also yawn, and they increase this behavior due to lack of oxygen.

Melbourne is the capital and most populous city of the Australian state of Victoria, and the second most populous city in Australia and Oceania. Its name refers to an urban agglomeration of 9,992.5 km2 (3,858.1 sq mi), comprising a metropolitan area with 31 municipalities, and is also the common name for its city centre. The city occupies much of the coastline of Port Phillip bay and spreads into the hinterlands towards the Dandenong and Macedon ranges, Mornington Peninsula and Yarra Valley. It has a population of approximately 5 million (19% of the population of Australia), and its inhabitants are referred to as "Melburnians".The city was founded on 30 August 1835, in what was the British colony of New South Wales, by free settlers from the colony of Van Diemen's Land. It was incorporated as a Crown settlement in 1837 and named in honour of the British Prime Minister, William Lamb, 2nd Viscount Melbourne. It was declared a city by Queen Victoria in 1847, after which it became the capital of the new colony of Victoria in 1851. In the wake of the 1850s Victorian gold rush, the city entered the "Marvellous Melbourne" boom period, transforming into one of the most important cities in the British Empire and one of the largest and wealthiest in the world. After the federation of Australia in 1901, it served as interim seat of government of the new nation until Canberra became the permanent capital in 1927. Today, it is a leading financial centre in the Asia-Pacific region and ranks 20th in the Global Financial Centres Index. The city is home to many of the best-known cultural institutions in the nation, such as the Melbourne Cricket Ground, the National Gallery of Victoria and the World Heritage-listed Royal Exhibition Building. It is also the birthplace of Australian impressionism, Australian rules football, the Australian film and television industries and Australian contemporary dance. More recently, it has been recognised as a UNESCO City of Literature and a global centre for street art, live music and theatre. It is the host city of annual international events such as the Australian Grand Prix, the Australian Open and the Melbourne Cup, and has also hosted the 1956 Summer Olympics and the 2006 Commonwealth Games. Due to it rating highly in entertainment, tourism and sport, as well as education, health care, research and development, the EIU currently ranks it the second most liveable city in the world. The main airport serving the city is Melbourne Airport (also referred to as Tullamarine Airport), which is the second busiest in Australia, and Australia's busiest seaport the Port of Melbourne. Its main metropolitan rail terminus is Flinders Street station and its main regional rail and road coach terminus is Southern Cross station. It also has the most extensive freeway network in Australia and the largest urban tram network in the world.

Vancouver is a coastal seaport city in western Canada, located in the Lower Mainland region of British Columbia. As the most populous city in the province, the 2016 census recorded 631,486 people in the city, up from 603,502 in 2011. The Greater Vancouver area had a population of 2,463,431 in 2016, making it the third-largest metropolitan area in Canada. Vancouver has the highest population density in Canada with over 5,400 people per square kilometre, which makes it the fifth-most densely populated city with over 250,000 residents in North America behind New York City, Guadalajara, San Francisco, and Mexico City according to the 2011 census. Vancouver is one of the most ethnically and linguistically diverse cities in Canada according to that census; 52% of its residents have a first language other than English. Roughly 30% of the city's inhabitants are of Chinese heritage. Vancouver is classed as a Beta global city.Vancouver is consistently named as one of the top five worldwide cities for livability and quality of life, and the Economist Intelligence Unit acknowledged it as the first city ranked among the top-ten of the world's most well-living cities for five consecutive years. Vancouver has hosted many international conferences and events, including the 1954 British Empire and Commonwealth Games, UN Habitat I, Expo 86, the World Police and Fire Games in 1989 and 2009; and the 2010 Winter Olympics and Paralympics which were held in Vancouver and Whistler, a resort community 125 km (78 mi) north of the city. In 2014, following thirty years in California, the TED conference made Vancouver its indefinite home. Several matches of the 2015 FIFA Women's World Cup were played in Vancouver, including the final at BC Place. The original settlement, named Gastown, grew up on clearcuts on the west edge of the Hastings Mill logging sawmill's property, where a makeshift tavern had been set up on a plank between two stumps and the proprietor, Gassy Jack, persuaded the curious millworkers to build him a tavern, on July 1, 1867. From that first enterprise, other stores and some hotels quickly appeared along the waterfront to the west. Gastown became formally laid out as a registered town site dubbed Granville, B.I. ("B.I" standing for "Burrard Inlet"). As part of the land and political deal whereby the area of the town site was made the railhead of the Canadian Pacific Railway (CPR), it was renamed "Vancouver" and incorporated shortly thereafter as a city, in 1886. By 1887, the Canadian Pacific transcontinental railway was extended westward to the city to take advantage of its large natural seaport to the Pacific Ocean, which soon became a vital link in a trade route between the Orient / East Asia, Eastern Canada, and Europe. As of 2014, Port Metro Vancouver is the third-largest port by tonnage in the Americas (recently displacing New York City), 27th in the world, [ the busiest and largest in Canada, and the most diversified port in North America. While forestry remains its largest industry, Vancouver is well known as an urban centre surrounded by nature, making tourism its second-largest industry. Major film production studios in Vancouver and nearby Burnaby have turned Greater Vancouver and nearby areas into one of the largest film production centres in North America, earning it the nickname "Hollywood North".

Abu Dhabi is the capital and the second most populous city of the United Arab Emirates (the most populous being Dubai), and also capital of the Emirate of Abu Dhabi, the largest of the UAE's seven emirates. Abu Dhabi lies on a T-shaped island jutting into the Persian Gulf from the central western coast. The city of Abu Dhabi has an estimated population of 1.8 million in 2016. Abu Dhabi houses federal government offices, is the seat of the United Arab Emirates Government, home to the Abu Dhabi Emiri Family and the President of the UAE, who is from this family. Abu Dhabi's rapid development and urbanisation, coupled with the relatively high average income of its population, has transformed the city into a large and advanced metropolis. Today the city is the country's centre of political and industrial activities, and a major cultural and commercial centre, due to its position as the capital. Abu Dhabi accounts for about two-thirds of the roughly $400-billion United Arab Emirates economy.Abu Dhabi is full of archaeological evidence that points to civilizations, such as the Umm an-Nar Culture, having been located there from the third millennium BCE. Settlements were also found farther outside the modern city of Abu Dhabi but closer to the modern city of Al Ain. There is evidence of Bronze Age Hafit period civilisation around the mountain of Hafeet (Jebel Hafeet). This location is very strategic because it is the UAE's second tallest mountain, so it would have great visibility. It also contains a lot of moisture in its springs and lakes, which means that there would have been more moisture thousands of years ago.The city of Abu Dhabi is on the southeastern side of the Arabian Peninsula, adjoining the Persian Gulf. Most of Abu Dhabi city is located on the island itself, but it has many suburban districts on the mainland, for example: Khalifa City A, B, and C; Khalifa City Al Raha Beach; Al Bahia City A, B, and C; Al Shahama; Al Rahba; Between Two Bridges; Baniyas; Shamkha; AL Wathba and Mussafah Residential.Gulf waters of Abu Dhabi holds the world's largest population of Indo-Pacific humpbacked dolphins.Abu Dhabi has a hot desert climate (Köppen climate classification BWh). Sunny blue skies can be expected throughout the year. The months of June through September are generally extremely hot and humid with maximum temperatures averaging above 38 °C (100 °F). During this time, sandstorms occur intermittently, in some cases reducing visibility to a few meters.The cooler season is from November to March, which ranges between moderately hot to mild. This period also sees dense fog on some days. On average, January is the coolest month in the year, while August is the hottest. Since the Tropic of Cancer passes through the emirate, the southern part falls within the Tropics. However, despite the coolest month having a 18.8 °C (65.8 °F) average, its climate is far too dry to be classed as tropical.Councils such as the Abu Dhabi Urban Planning Council and the Regulation and Supervision Bureau are responsible for infrastructure projects in the city. Finances are mainly through the state government.Because Abu Dhabi is the capital of the UAE, the presidents office is located here.

Afghanistan is a landlocked country with estimated population at at 29.2 million in 2017.Human habitation in Afghanistan dates back to the Middle Paleolithic Era, and the country's strategic location along the Silk Road connected it to the cultures of the Middle East and other parts of Asia. The land has historically been home to various peoples and has witnessed numerous military campaigns, including those by Alexander the Great, Mauryas, Muslim Arabs, Mongols, British, Soviets, and since 2001 by the United States with NATO-allied countries. It has been called "unconquerable"" and nicknamed the "graveyard of empires". The land also served as the source from which the Kushans, Hephthalites, Samanids, Saffarids, Ghaznavids, Ghorids, Khaljis, Mughals, Hotaks, Durranis, and others have risen to form major empires. The political history of the modern state of Afghanistan began with the Hotak and Durrani dynasties in the 18th century. In the late 19th century, Afghanistan became a buffer state in the "Great Game" between British India and the Russian Empire. By 1996 most of Afghanistan was captured by the Islamic fundamentalist group the Taliban, who ruled most of the country as a totalitarian regime for over five years. The Taliban were forcibly removed by the NATO-led coalition, and a new democratically-elected government political structure was formed.Afghanistan is a unitary presidential Islamic republic with a population of 31 million, mostly composed of ethnic Pashtuns, Tajiks, Hazaras and Uzbeks. It is a member of the United Nations, the Organisation of Islamic Cooperation, the Group of 77, the Economic Cooperation Organization, and the Non-Aligned Movement. Afghanistan's economy is the world's 108th largest, with a GDP of $64.08 billion; the country fares much worse in terms of per-capita GDP (PPP), ranking 167th out of 186 countries in a 2016 report from the International Monetary Fund.Michael E. O'Hanlon of the Brookings Institution estimated that if Afghanistan generates about $10 billion per year from its mineral deposits, its gross national product would double and provide long-term funding for Afghan security forces and other critical needs. The United States Geological Survey (USGS) estimated in 2006 that northern Afghanistan has an average 2.9 billion (bn) barrels (bbl) of crude oil, 15.7 trillion cubic feet (440 bn m3) of natural gas, and 562 million bbl of natural gas liquids.[ In 2011, Afghanistan signed an oil exploration contract with China National Petroleum Corporation (CNPC) for the development of three oil fields along the Amu Darya river in the north. The country has significant amounts of lithium, copper, gold, coal, iron ore, and other minerals. The Khanashin carbonatite in Helmand Province contains 1,000,000 metric tons (1,100,000 short tons) of rare earth elements. In 2007, a 30-year lease was granted for the Aynak copper mine to the China Metallurgical Group for $3 billion, making it the biggest foreign investment and private business venture in Afghanistan's history. The state-run Steel Authority of India won the mining rights to develop the huge Hajigak iron ore deposit in central Afghanistan. Government officials estimate that 30% of the country's untapped mineral deposits are worth at least $1 trillion. One official asserted that "this will become the backbone of the Afghan economy" and a Pentagon memo stated that Afghanistan could become the "Saudi Arabia of lithium". In a 2011 news story, the CSM reported, "The United States and other Western nations that have borne the brunt of the cost of the Afghan war have been conspicuously absent from the bidding process on Afghanistan's mineral deposits, leaving it mostly to regional powers."

Alaska is a U.S. state in the northwest extremity of North America. The Canadian administrative divisions of British Columbia and Yukon border the state to the east, its most extreme western part is Attu Island, and it has a maritime border with Russia (Chukotka Autonomous Okrug) to the west across the Bering Strait. To the north are the Chukchi and Beaufort seas-the southern parts of the Arctic Ocean. The Pacific Ocean lies to the south and southwest. It is the largest state in the United States by area and the seventh largest subnational division in the world. In addition, it is the 3rd least populous and the most sparsely populated of the 50 United States; nevertheless, it is by far the most populous territory located mostly north of the 60th parallel in North America: its population-estimated at 738,432 by the U.S. Census Bureau in 2015[5]- is more than quadruple the combined populations of Northern Canada and Greenland. Approximately half of Alaska's residents live within the Anchorage metropolitan area. Alaska's economy is dominated by the fishing, natural gas, and oil industries, resources which it has in abundance. Military bases and tourism are also a significant part of the economy.The United States purchased Alaska from the Russian Empire on March 30, 1867, for 7.2 million U.S. dollars at approximately two cents per acre ($4.74/km2). The area went through several administrative changes before becoming organized as a territory on May 11, 1912. It was admitted as the 49th state of the U.S. on January 3, 1959.The Interior is the largest region of Alaska; much of it is uninhabited wilderness. Fairbanks is the only large city in the region. Denali National Park and Preserve is located here. Denali is the highest mountain in North America.Alaska has more than three million lakes. Marshlands and wetland permafrost cover 188,320 square miles (487,747 km2) (mostly in northern, western and southwest flatlands). Glacier ice covers about 28,957 square miles (75,000 km2) of Alaska. The Bering Glacier is the largest glacier in North America, covering 2,008 square miles (5,200 km2) alone.In 1960, the Census Bureau reported Alaska's population as 77.2% White, 3% Black, and 18.8% American Indian and Alaska Native.According to the 2010 United States Census, Alaska, had a population of 710,231. In terms of race and ethnicity, the state was 66.7% White (64.1% Non-Hispanic White), 14.8% American Indian and Alaska Native, 5.4% Asian, 3.3% Black or African American, 1.0% Native Hawaiian and Other Pacific Islander, 1.6% from Some Other Race, and 7.3% from Two or More Races. Hispanics or Latinos of any race made up 5.5% of the population. As of 2011, 50.7% of Alaska's population younger than one year of age belonged to minority groups (i.e., did not have two parents of non-Hispanic white ancestry).

Native Americans, also known as American Indians, Indigenous Americans and other terms, are the indigenous peoples of the United States, except Hawaii. There are over 500 federally recognized tribes within the US, about half of which are associated with Indian reservations. The term "American Indian" excludes Native Hawaiians and some Alaska Natives, while Native Americans (as defined by the US Census) are American Indians, plus Alaska Natives of all ethnicities. Native Hawaiians are not counted as Native Americans by the US Census, instead being included in the Census grouping of "Native Hawaiian and other Pacific Islander".The ancestors of modern Native Americans arrived in what is now the United States at least 15,000 years ago, possibly much earlier, from Asia via Beringia. A vast variety of peoples, societies and cultures subsequently developed. Native Americans were greatly affected by the European colonization of the Americas, which began in 1492, and their population declined precipitously mainly due to introduced diseases as well as warfare, territorial confiscation and slavery. After the founding of the United States, many Native American peoples were subjected to warfare, removals and one-sided treaties, and they continued to suffer from discriminatory government policies into the 20th century. Since the 1960s, Native American self-determination movements have resulted in changes to the lives of Native Americans, though there are still many contemporary issues faced by Native Americans. Today, there are over five million Native Americans in the United States, 78% of whom live outside reservations.When the United States was created, established Native American tribes were generally considered semi-independent nations, as they generally lived in communities separate from British settlers. The federal government signed treaties at a government-to-government level until the Indian Appropriations Act of 1871 ended recognition of independent native nations, and started treating them as "domestic dependent nations" subject to federal law. This law did preserve the rights and privileges agreed to under the treaties, including a large degree of tribal sovereignty. For this reason, many (but not all) Native American reservations are still independent of state law and actions of tribal citizens on these reservations are subject only to tribal courts and federal law.The Indian Citizenship Act of 1924 granted U.S. citizenship to all Native Americans born in the United States who had not yet obtained it. This emptied the "Indians not taxed" category established by the United States Constitution, allowed natives to vote in state and federal elections, and extended the Fourteenth Amendment protections granted to people "subject to the jurisdiction" of the United States. However, some states continued to deny Native Americans voting rights for several decades. Bill of Rights protections do not apply to tribal governments, except for those mandated by the Indian Civil Rights Act of 1968.In 2009, an "apology to Native Peoples of the United States" was included in the defense appropriations act. It states that the U.S. "apologizes on behalf of the people of the United States to all Native Peoples for the many instances of violence, maltreatment, and neglect inflicted on Native Peoples by citizens of the United States".The census counted 248,000 Indians in 1890, 332,000 in 1930 and 334,000 in 1940, including those on and off reservations in the 48 states. Total spending on Indians averaged $38 million a year in the late 1920s, dropping to a low of $23 million in 1933, and returning to $38 million in 1940.

San Diego: Spanish for "Saint Didacus" is a city in the U.S. state of California. It is in San Diego County, on the coast of the Pacific Ocean in Southern California, approximately 120 miles (190 km) south of Los Angeles and immediately adjacent to the border with Mexico.With an estimated population of 1,419,516 as of July 1, 2017. San Diego is the eighth-largest city in the United States and second-largest in California. It is part of the San Diego-Tijuana conurbation, the second-largest transborder agglomeration between the U.S. and a bordering country after Detroit-Windsor, with a population of 4,922,723 people. The city is known for its mild year-round climate, natural deep-water harbor, extensive beaches, long association with the United States Navy, and recent emergence as a healthcare and biotechnology development center.San Diego has been called "the birthplace of California." Historically home to the Kumeyaay people, it was the first site visited by Europeans on what is now the West Coast of the United States. Upon landing in San Diego Bay in 1542, Juan Rodríguez Cabrillo claimed the area for Spain, forming the basis for the settlement of Alta California 200 years later. The Presidio and Mission San Diego de Alcalá, founded in 1769, formed the first European settlement in what is now California. In 1821, San Diego became part of the newly independent Mexico, which reformed as the First Mexican Republic two years later. California became part of the United States in 1848 following the Mexican-American War and was admitted to the union as a state in 1850.The city is the seat of San Diego County and is the economic center of the region as well as the San Diego-Tijuana metropolitan area. San Diego's main economic engines are military and defense-related activities, tourism, international trade, and manufacturing. The presence of the University of California, San Diego (UCSD), with the affiliated UCSD Medical Center, has helped make the area a center of research in biotechnology.

Los Angeles is the most populous city in California and the second most populous city in the United States, after New York City. With an estimated population of four million, Los Angeles is the cultural, financial, and commercial center of Southern California. Nicknamed the "City of Angels" partly because of its name's Spanish meaning, Los Angeles is known for its Mediterranean climate, ethnic diversity, Hollywood and the entertainment industry, and sprawling metropolis.Los Angeles is located in a large basin bounded by the Pacific Ocean on one side and by mountains as high as 10,000 feet (3,000 m) on the others. The city proper, which covers about 469 square miles (1,210 km2), is the seat of Los Angeles County, the most populated county in the country. Los Angeles is also the principal city of the Los Angeles metropolitan area, the second largest in the United States after that of New York City, with a population of 13.1 million. It is part of the Los Angeles-Long Beach combined statistical area, also the second most populous in the nation with a 2015 estimated population of 18.7 million. Los Angeles is one of the most substantial economic engines within the United States, with a diverse economy in a broad range of professional and cultural fields. Los Angeles is also famous as the home of Hollywood, a major center of the world entertainment industry. A global city, it has been ranked 6th in the Global Cities Index and 9th in the Global Economic Power Index. The Los Angeles combined statistical area also has a gross metropolitan product of $831 billion (as of 2008), making it the third-largest in the world, after the Tokyo and New York metropolitan areas. Los Angeles hosted the 1932 and 1984 Summer Olympics and will host the event for a third time in 2028. The city also hosted the Miss Universe pageant twice, in 1990 and 2006, and was one of 9 American cities to host the 1994 FIFA men's soccer World Cup and one of 8 to host the 1999 FIFA women's soccer World Cup, hosting the final match for both tournaments.Historically home to the Chumash and Tongva, Los Angeles was claimed by Juan Rodríguez Cabrillo for Spain in 1542 along with the rest of what would become Alta California. The city was officially founded on September 4, 1781, by Spanish governor Felipe de Neve. It became a part of Mexico in 1821 following the Mexican War of Independence. In 1848, at the end of the Mexican-American War, Los Angeles and the rest of California were purchased as part of the Treaty of Guadalupe Hidalgo, becoming part of the United States. Los Angeles was incorporated as a municipality on April 4, 1850, five months before California achieved statehood. The discovery of oil in the 1890s brought rapid growth to the city. The completion of the Los Angeles Aqueduct in 1913, delivering water from Eastern California, later assured the city's continued rapid growth.According to a 2014 study by the Pew Research Center, Christianity is the most prevalently practiced religion in Los Angeles (65%).The economy of Los Angeles is driven by international trade, entertainment (television, motion pictures, video games, music recording, and production), aerospace, technology, petroleum, fashion, apparel, and tourism.[ Other significant industries include finance, telecommunications, law, healthcare, and transportation.

Texas is the second largest state in the United States by both area and population. Geographically located in the South Central region of the country, Houston is the most populous city in Texas and the fourth largest in the U.S., while San Antonio is the second-most populous in the state and seventh largest in the U.S. Dallas-Fort Worth and Greater Houston are the fourth and fifth largest metropolitan statistical areas in the country, respectively. Other major cities include Austin, the second-most populous state capital in the U.S., and El Paso. Texas is nicknamed "The Lone Star State" to signify its former status as an independent republic, and as a reminder of the state's struggle for independence from Mexico. The "Lone Star" can be found on the Texas state flag and on the Texan state seal. The origin of Texas's name is from the word taysha, which means "friends" in the Caddo language. Due to its size and geologic features such as the Balcones Fault, Texas contains diverse landscapes common to both the U.S. Southern and Southwestern regions. Although Texas is popularly associated with the U.S. southwestern deserts, less than 10% of Texas's land area is desert. Most of the population centers are in areas of former prairies, grasslands, forests, and the coastline. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, and finally the desert and mountains of the Big Bend.The term "six flags over Texas refers to several nations that have ruled over the territory. Spain was the first European country to claim the area of Texas. France held a short-lived colony. Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the union as the 28th state. The state's annexation set off a chain of events that led to the Mexican-American War in 1846. A slave state before the American Civil War, Texas declared its secession from the U.S. in early 1861, and officially joined the Confederate States of America on March 2 of the same year. After the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation.Historically four major industries shaped the Texas economy prior to World War II: cattle and bison, cotton, timber, and oil. Before and after the U.S. Civil War the cattle industry, which Texas came to dominate, was a major economic driver for the state, thus creating the traditional image of the Texas cowboy. In the later 19th century cotton and lumber grew to be major industries as the cattle industry became less lucrative. It was ultimately, though, the discovery of major petroleum deposits (Spindletop in particular) that initiated an economic boom which became the driving force behind the economy for much of the 20th century. With strong investments in universities, Texas developed a diversified economy and high tech industry in the mid-20th century. As of 2015, it is second on the list of the most Fortune 500 companies with 54. With a growing base of industry, the state leads in many industries, including agriculture, petrochemicals, energy, computers and electronics, aerospace, and biomedical sciences. Texas has led the U.S. in state export revenue since 2002, and has the second-highest gross state product. If Texas were a sovereign state, it would be the 10th largest economy in the world.

Geologically is a long, narrow inlet with steep sides or cliffs, created by a glacier. There are many fjords on the coasts of Alaska, Antarctica, British Columbia, Chile, Greenland, the Faroe Islands, Iceland, Kamchatka, the Kerguelen Islands, New Zealand, Norway, Novaya Zemlya, Labrador, Nunavut, Newfoundland, Quebec, Scotland, South Georgia Island, and Washington state. Norway's coastline is estimated at 29,000 kilometres (18,000 mi) with nearly 1,200 fjords, but only 2,500 kilometres (1,600 mi) when fjords are excluded.A true fjord is formed when a glacier cuts a U-shaped valley by ice segregation and abrasion of the surrounding bedrock. According to the standard model, glaciers formed in pre-glacial valleys with a gently sloping valley floor. The work of the glacier then left an over deepened U-shaped valley that ends abruptly at a valley or trough end. Such valleys are fjords when flooded by the ocean. Thresholds above sea level create freshwater lakes. Glacial melting is accompanied by the rebounding of Earth's crust as the ice load and eroded sediment is removed (also called isostasy or glacial rebound). In some cases this rebound is faster than sea level rise. Most fjords are deeper than the adjacent sea; Sogne fjord, Norway, reaches as much as 1,300 m (4,265 ft) below sea level. Fjords generally have a sill or shoal (bedrock) at their mouth caused by the previous glacier's reduced erosion rate and terminal moraine. In many cases this sill causes extreme currents and large saltwater rapids (see skookumchuck). Saltstraumen in Norway is often described as the world's strongest tidal current. These characteristics distinguish fjords from rias (e.g. the Bay of Kotor), which are drowned valleys flooded by the rising sea. Drammensfjorden is cut almost in two by the Svelvik "ridge", a sandy moraine that during the ice cover was under sea level but after the post-glacial rebound reaches 60 m (200 ft) above the fjord.In Scandinavia, fjord is used for a narrow inlet of the sea in Norway, Denmark and western Sweden, but this is not its only application. In Norway and Iceland, the usage is closest to the Old Norse, with fjord used for both a firth and for a long, narrow inlet. In eastern Norway, the term is also applied to long narrow freshwater lakes (for instance Mjøsa [commonly referred to as fjorden], Randsfjorden and Tyrifjorden) and sometimes even to rivers (in local usage, for instance in Flå in Hallingdal, the Hallingdal river is referred to as fjorden). In southeast Sweden, the name fjard fjärd is a subdivision of the term 'fjord' used for bays, bights and narrow inlets on the Swedish Baltic Sea coast, and in most Swedish lakes. This latter term is also used for bodies of water off the coast of Finland where Finland Swedish is spoken. In Danish, the word may even apply to shallow lagoons. In modern Icelandic, fjörður is still used with the broader meaning of firth or inlet. In Faroese fjørður is used both about inlets and about broader sounds, whereas a narrower sound is called sund. In the Finnish language, a word vuono is used although there is only one fjord in Finland. Small waterfalls within these fjords are also used as freshwater resources for the people of Scandinavia and, in particular, Norway.

The National Museum of China (Chinese: 中国国家博物馆; pinyin: Zhōngguó guójiā bówùguǎn) flanks the eastern side of Tiananmen Square in Beijing, China. The museum's mission is to educate about the arts and history of China. It is directed by the Ministry of Culture of the People's Republic of China.It is one of the largest museums in the world, and with over eight million visitors in 2017, the National Museum of China was the second-most visited art museum in the world, just after the Louvre.The museum was established in 2003 by the merging of the two separate museums that had occupied the same building since 1959: the Museum of the Chinese Revolution in the northern wing (originating in the Office of the National Museum of the Revolution founded in 1950 to preserve the legacy of the 1949 revolution) and the National Museum of Chinese History in the southern wing (with origins in both the Beijing National History Museum, founded in 1949, and the Preliminary Office of the National History Museum, founded in 1912, tasked to safeguard China's larger historical legacy).The building was completed in 1959 as one of the Ten Great Buildings celebrating the ten-year anniversary of the founding of the People's Republic of China. It complements the opposing Great Hall of the People that was built at the same time. The structure sits on 6.5 hectares (16 acres) and has a frontal length of 313 metres (1,027 ft), a height of four stories totaling 40 metres (130 ft), and a width of 149 metres (489 ft). The front displays ten square pillars at its center.After four years of renovation, the museum reopened on March 17, 2011, with 28 new exhibition halls, more than triple the previous exhibition space, and state of the art exhibition and storage facilities. It has a total floor space of nearly 200,000 m2 (2.2 million square feet) to display. The renovations were designed by the German firm Gerkan, Marg and Partners.The museum, covering Chinese history from the Yuanmou Man of 1.7 million years ago to the end of the Qing Dynasty (the last imperial dynasty in Chinese history), has a permanent collection of 1,050,000 items, with many precious and rare artifacts not to be found in museums anywhere else in China or the rest of the world. Among the most important items in the National Museum of China are the "Simuwu Ding" from the Shang Dynasty (the heaviest piece of ancient bronzeware in the world, at 832.84 kg), the square shaped Shang Dynasty bronze zun decorated with four sheep heads, a large and rare inscribed Western Zhou Dynasty bronze water pan, a gold-inlaid Qin Dynasty bronze tally in the shape of a tiger, Han Dynasty jade burial suits sewn with gold thread, and a comprehensive collection of Tang Dynasty tri-colored glazed sancai and Song Dynasty ceramics. The museum also has an important numismatic collection, including 15,000 coins donated by Luo Bozhao.
