  Bordeaux
  Coordinates: 44°50′19″N 0°34′42″W / 44.8386°N 0.5783°W / 44.8386; -0.5783
  Bordeaux (French pronunciation: [bɔʁdo]; Gascon: Bordèu; Basque: Bordele) is a port city on the Garonne River in the Gironde department in southwestern France.
  The Bordeaux metropolitan area has a population of 1,105,000 and constitutes the sixth-largest urban area in France. It is the capital of the Aquitaine region, as well as the prefecture of the Gironde department. Its inhabitants are called Bordelais.
  Bordeaux is the world's major wine industry capital. It is home to the world's main wine fair, Vinexpo, while the wine economy in the metro area moves 14.5 billion euros each year.Bordeaux wine has been produced in the region since the 8th century. The historic part of the city is on the UNESCO World Heritage List as "an outstanding urban and architectural ensemble" of the 18th century.
  Between 30,000 and 20,000 years ago the area of Bordeaux was inhabited by the Neanderthal, whose remains have been found at a famous cave known as Pair-non-Pair, near Bourg sur Gironde, just north of Bordeaux. In historical times, around 300 BC it was the settlement of a Celtic tribe, the Bituriges Vivisci, who named the town Burdigala, probably of Aquitainian origin. The name Bourde is still the name of a river south of the city.

  Brazil
  Brazil ⁱ/brəˈzɪl/ (Portuguese: Brasil, IPA: [bɾaˈziw]), officially the Federative Republic of Brazil (Portuguese: República Federativa do Brasil,  listen (help·info)), is the largest country in South America. It is the world's fifth largest country, both by geographical area and by population with over 192 million people. It is the only Portuguese-speaking country in the Americas and the largest lusophone country in the world.
  Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 km (4,655 mi). It is bordered on the north by Venezuela, Guyana, Suriname and the French overseas region of French Guiana; on the northwest by Colombia; on the west by Bolivia and Peru; on the southwest by Argentina and Paraguay and on the south by Uruguay. Numerous archipelagos form part of Brazilian territory, such as Fernando de Noronha, Rocas Atoll, Saint Peter and Paul Rocks, and Trindade and Martim Vaz. It borders all other South American countries except Ecuador and Chile.
  Brazil was a colony of Portugal from the landing of Pedro Álvares Cabral in 1500 until 1815, when it was elevated to the rank of kingdom and the United Kingdom of Portugal, Brazil and the Algarves was formed. The colonial bond was in fact broken in 1808, when the capital of the Portuguese colonial empire was transferred from Lisbon to Rio de Janeiro, after Napoleon invaded Portugal.Independence was achieved in 1822 with the formation of the Empire of Brazil, a unitary state governed under a constitutional monarchy and a parliamentary system. The country became a presidential republic in 1889, when a military coup d'état proclaimed the Republic, although the bicameral legislature, now called Congress, dates back to the ratification of the first constitution in 1824. Its current Constitution, formulated in 1988, defines Brazil as a Federal Republic. The Federation is formed by the union of the Federal District, the 26 States, and the 5,564 Municipalities.

  Canada
  Canada ( /ˈkænədə/) is a North American country consisting of ten provinces and three territories. Located in the northern part of the continent, it extends from the Atlantic Ocean in the east to the Pacific Ocean in the west, and northward into the Arctic Ocean. Spanning over 9,900,000 km² (3,800,000 sq mi), Canada is the world's second-largest country by total area, and its common border with the United States is the longest land border in the world.
  The land that is now Canada has been inhabited for millennia by various Aboriginal peoples. Beginning in the late 15th century, British and French colonial expeditions explored, and later settled, along the region's Atlantic coast. France ceded nearly all of its colonies in North America in 1763 after the Seven Years' War. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces and territories and a process of increasing autonomy; the Canada Act 1982 severed the vestiges of legal dependence on Britain.

  Dominican Republic
  The Dominican Republic (ⁱ/dəˌmɪnɨkən rɨˈpʌblɪk/; Spanish: República Dominicana [reˈpuβlika ðominiˈkana]) is a nation on the island of Hispaniola, part of the Greater Antilles archipelago in the Caribbean region. The western third of the island is occupied by the nation of Haiti, making Hispaniola one of two Caribbean islands that are shared by two countries. Both by area and population, the Dominican Republic is the second largest Caribbean nation (after Cuba), with 48,442 square kilometres (18,704 sq mi) and an estimated 10 million people.
  Taínos inhabited what is now the Dominican Republic since the 7th century. Christopher Columbus landed on it in 1492, and it became the site of the first permanent European settlement in the Americas, namely Santo Domingo, the country's capital and Spain's first capital in the New World. Santo Domingo can boast of many firsts in the Americas, including the first cathedral, and castle, both in the Ciudad Colonial area, a UNESCO World Heritage Site.

  France
  France (English ⁱ/ˈfræns/ FRANSS or /ˈfrɑːns/ FRAHNSS; French: [fʁɑ̃s] ( listen)), officially the French Republic (French: République française [ʁepyblik fʁɑ̃sɛz]), is a unitary semi-presidential republic in Western Europe with several overseas territories and islands located on other continents and in the Indian, Pacific, and Atlantic oceans. Metropolitan France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. It is often referred to as l’Hexagone ("The Hexagon") because of the geometric shape of its territory. It is the largest western European country and it possesses the second-largest exclusive economic zone in the world, covering 11,035,000 km² (4,260,000 sq mi), just behind that of the United States (11,351,000 km² / 4,383,000 sq mi).
  Over the past 500 years, France has been a major power with strong cultural, economic, military and political influence in Europe and around the world. During the 17th and 18th centuries, France colonised great parts of North America and Southeast Asia; during the 19th and early 20th centuries, France built the second largest colonial empire of the time, including large portions of North, West and Central Africa, Southeast Asia, and many Caribbean and Pacific Islands.

  Greenwich
  Coordinates: 51°28′45″N 0°00′00″E / 51.4791°N 0.0000°E / 51.4791; 0.0000
  Greenwich (UK ⁱ/ɡrɪnɪdʒ/ GRIN-ij; US /ɡrɛnɪtʃ/ GREN-ich or /ɡrɛnɪdʒ/ GREN-ij) is a district of south London, England, located in the Royal Borough of Greenwich and situated 5.5 miles (8.9 km) east south-east of Charing Cross.
  Greenwich is notable for its maritime history and for giving its name to the Greenwich Meridian (0° longitude) and Greenwich Mean Time. The town became the site of a royal palace, the Palace of Placentia from the 15th century, and was the birthplace of many in the House of Tudor, including Henry VIII and Elizabeth I. The palace fell into disrepair during the English Civil War and was rebuilt as the Royal Naval Hospital for Sailors by Sir Christopher Wren and his assistant Nicholas Hawksmoor. These buildings became the Royal Naval College in 1873, and they remained an establishment for military education until 1998 when they passed into the hands of the Greenwich Foundation. The historic rooms within these buildings remain open to the public; other buildings are used by University of Greenwich and the Trinity College of Music.

  The North Atlantic Treaty Organization or NATO ( /ˈneɪtoʊ/ NAY-toh; French: Organisation du traité de l'Atlantique Nord (OTAN)), also called the (North) Atlantic Alliance, is an intergovernmental military alliance based on the North Atlantic Treaty which was signed on 4 April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defense in response to an attack by any external party. NATO's headquarters are in Brussels, Belgium, one of the 28 member states across North America and Europe, the newest of which, Albania and Croatia, joined in April 2009. An additional 22 countries participate in NATO's Partnership for Peace, with 15 other countries involved in institutionalized dialogue programs. The combined military spending of all NATO members constitutes over 70% of the world's defence spending.
  For its first few years, NATO was not much more than a political association. However, the Korean War galvanized the member states, and an integrated military structure was built up under the direction of two U.S. supreme commanders. The course of the Cold War led to a rivalry with nations of the Warsaw Pact, which formed in 1955. The first NATO Secretary General, Lord Ismay, stated in 1949 that the organization's goal was "to keep the Russians out, the Americans in, and the Germans down." Doubts over the strength of the relationship between the European states and the United States ebbed and flowed, along with doubts over the credibility of the NATO defence against a prospective Soviet invasion—doubts that led to the development of the independent French nuclear deterrent and the withdrawal of the French from NATO's military structure in 1966.

  New Orleans
  New Orleans ( /nuː ˈɔrliənz/ or /ˈnuː ɔrˈliːnz/, locally /nuː ˈɔrlənz/ or /ˈnɔrlənz/; French: La Nouvelle-Orléans [la nuvɛlɔʁleɑ̃] ( listen)) is a major United States port and the largest city and metropolitan area in the state of Louisiana. The population of the city proper was 343,829 as of the 2010 U.S. Census. The New Orleans metropolitan area (New Orleans–Metairie–Kenner Metropolitan Statistical Area) had a population of 1,167,764 in 2010 and was the 46th largest in the United States. The New Orleans–Metairie–Bogalusa Combined Statistical Area, a larger trading area, had a 2010 population of 1,214,932.
  The city is named after Philippe d'Orléans, Duke of Orléans, Regent of France, and is well known for its distinct French Creole architecture, as well as its cross-cultural and multilingual heritage. New Orleans is also famous for its cuisine, music (particularly as the birthplace of jazz), and its annual celebrations and festivals, most notably Mardi Gras. The city is often referred to as the "most unique" in America.

  Newlyn
  Coordinates: 50°06′04″N 5°33′11″W / 50.101°N 5.553°W / 50.101; -5.553
  Newlyn (Cornish: Lulyn) is a town and fishing port in southwest Cornwall, England, United Kingdom.
  Newlyn forms a conurbation with the neighbouring town of Penzance and is part of Penzance civil parish, and is the southernmost town on the British mainland (though not the most southerly settlement). The principal industry in Newlyn is fishing.
  The settlement is recorded as Nulyn in 1279 and as Lulyn in 1290, and the name is thought to be derived from the Cornish for "pool for a fleet of boats" which is thought to refer to the shallows offshore also called Gwavas Lake, traditionally the principal mooring for the fishing fleet in the area.
  Before the rise of Newlyn as an important settlement the landing rights and most property within the Newlyn area were owned by the Manor of Alverton. Newlyn's history has been strongly linked to its role as a major fishing port. The natural protection afforded by the Gwavas Lake (an area of seawater in Mounts Bay) led to many local fishermen using this area as a preferred landing site. Newlyn harbour is first recorded in 1435 by the Bishop of Exeter; later large-scale improvements to the harbour led to Newlyn becoming the predominant fishing port in Mounts Bay.

  North pole
  Coordinates: 90°N 0°W / 90°N 0°W / 90; -0
  The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is, subject to the caveats explained below, defined as the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It should not be confused with the North Magnetic Pole.
  The North Pole is the northernmost point on Earth, lying diametrically opposite the South Pole. It defines geodetic latitude 90° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value.
  While the South Pole lies on a continental land mass, the North Pole is located in the middle of the Arctic Ocean amid waters that are almost permanently covered with constantly shifting sea ice. This makes it impractical to construct a permanent station at the North Pole (unlike the South Pole). However, the Soviet Union, and later Russia, have constructed a number of manned drifting stations on a generally annual basis since 1937, some of which have passed over or very close to the Pole. In recent years, a number of studies have predicted that the North Pole may become seasonally ice-free due to Arctic shrinkage, with timescales varying from next year to fifty years or more.

  Quebec /kwəˈbɛk/ or /kəˈbɛk/ (French: Québec [kebɛk] ( listen)) is a province in east-central Canada. It is the only Canadian province with a predominantly French-speaking population and the only one whose sole official language is French at the provincial level.
  Quebec is Canada's largest province by area and its second-largest administrative division; only the territory of Nunavut is larger. It is bordered to the west by the province of Ontario, James Bay and Hudson Bay, to the north by Hudson Strait and Ungava Bay, to the east by the Gulf of Saint Lawrence and the provinces of Newfoundland and Labrador and New Brunswick. It is bordered on the south by the US states of Maine, New Hampshire, Vermont, and New York. It also shares maritime borders with Nunavut, Prince Edward Island, and Nova Scotia.
  Quebec is Canada's second most populous province, after Ontario. Most inhabitants live in urban areas near the Saint Lawrence River between Montreal and Quebec City, the capital. English-speaking communities and English-language institutions are concentrated in the west of the island of Montreal but are also significantly present in the Outaouais, Eastern Townships, and Gaspé regions. The Nord-du-Québec region, occupying the northern half of the province, is sparsely populated and inhabited primarily by Aboriginal peoples.

  Quito
  San Francisco de Quito, most often called Quito (Spanish pronunciation: [ˈkito]), is the capital city of Ecuador in northwestern South America. It is located in north-central Ecuador in the Guayllabamba river basin, on the eastern slopes of Pichincha, an active stratovolcano in the Andes mountains. With a population of 2,197,698 according to the last census (2001), and, as estimated by the municipality, approximately 2,504,991 in 2005, Quito is the second most populous city in Ecuador, after Guayaquil. It is also the capital of the Pichincha province and the seat of Metropolitan District of Quito. The canton recorded a population of 1,842,201 residents in the 2001 national census. In 2008, the city was designated as the headquarters of the Union of South American Nations.
  The elevation of the city's central square (Plaza de la Independencia or Plaza Grande) is 2,800 metres (9,200 ft), making Quito the second-highest administrative capital city in the world (after La Paz, Bolivia), and the highest legal capital (ahead of Sucre, also in Bolivia, and Bogotá, Colombia).

  Rimouski
  Rimouski is a Canadian city located in the Bas-Saint-Laurent (Quebec) region at the mouth of the Rimouski River. It has a population of 46,860 (as of 2011) and many touristic, cultural and industrial attractions.
  Rimouski classifies itself as a “students' city” thanks to the many educational institutions, such as the Université du Québec à Rimouski (UQAR), the Cégep de Rimouski (which includes the Institut Maritime du Québec (IMQ)) and the Music Conservatory. It is also the home of some important ocean sciences research centers.
  The city was founded by Sir René Lepage de Ste-Claire in 1696. Originally from Ouanne in the Burgundy region, he exchanged property he owned on the Île d'Orléans with Augustin Rouer de la Cardonnière for the Seigneurie of Rimouski, which extended along the St. Lawrence River from the Hâtée River at Le Bic to the Métis River. De la Cardonnière had been the owner of Rimouski since 1688, but had never lived there. René Lepage moved his family to Rimouski, where it held the seigneurie until 1780 when it was gradually sold to the Quebec City businessman Joseph Drapeau.

  Saint Petersburg
  Saint Petersburg (Russian: Санкт-Петербург, tr. Sankt-Peterburg; IPA: [sankt pʲɪtʲɪrˈburk] ( listen)) is a city and a federal subject (a federal city) of Russia located on the Neva River at the head of the Gulf of Finland on the Baltic Sea. In 1914 the name of the city was changed to Petrograd (Russian: Петроград; IPA: [pʲɪtrɐˈgrat]), in 1924 to Leningrad (Russian: Ленинград; IPA: [lʲɪnʲɪnˈgrat]) and in 1991 back to Saint Petersburg.
  In Russian literature, informal documents, and discourse, the "Saint" (Санкт-) is usually omitted, leaving Petersburg (Петербург, Peterburg). In common parlance Russians may drop "-burg" (-бург) as well, leaving only Peter (Питер, Russian: [ˈpʲitʲɪr]).
  Saint Petersburg was founded by Tsar Peter the Great on May 27 [O.S. 16] 1703. From 1713 to 1728 and from 1732 to 1918, Saint Petersburg was the Imperial capital of Russia. In 1918 the central government bodies moved from Saint Petersburg (then named Petrograd) to Moscow. It is Russia's second largest city after Moscow with almost 5 million inhabitants. Saint Petersburg is a major European cultural center, and also an important Russian port on the Baltic Sea.

  Scotland
  Scotland (Scottish Gaelic: Alba ([ˈalˠ̪apə]  listen (help·info))) is a country that is part of the United Kingdom. Occupying the northern third of the island of Great Britain, it shares a border with England to the south and is bounded by the North Sea to the east, the Atlantic Ocean to the north and west, and the North Channel and Irish Sea to the southwest. In addition to the mainland, Scotland constitutes over 790 islands including the Northern Isles and the Hebrides.
  Edinburgh, the country's capital and second largest city, is one of Europe's largest financial centres. Edinburgh was the hub of the Scottish Enlightenment of the 18th century, which transformed Scotland into one of the commercial, intellectual and industrial powerhouses of Europe. Glasgow, Scotland's largest city, was once one of the world's leading industrial cities and now lies at the centre of the Greater Glasgow conurbation. Scottish waters consist of a large sector of the North Atlantic and the North Sea, containing the largest oil reserves in the European Union. This has given Aberdeen, the third largest city in Scotland, the title of Europe's oil capital.

  The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is one of the two points where the Earth's axis of rotation intersects its surface. It is the southernmost point on the surface of the Earth and lies on the opposite side of the Earth from the North Pole. Situated on the continent of Antarctica, it is the site of the United States Amundsen-Scott South Pole Station, which was established in 1956 and has been permanently staffed since that year. The Geographic South Pole should not be confused with the South Magnetic Pole, which though geographically nearby, is defined based on the Earth's magnetic field.
  For most purposes, the Geographic South Pole is defined as the southern point of the two points where the Earth's axis of rotation intersects its surface (the other being the Geographic North Pole). However, the Earth's axis of rotation is actually subject to very small 'wobbles', so this definition is not adequate for very precise work; see Polar Motion for further information.

  Tropic of Cancer
  Coordinates: 23°26′16″N 0°0′0″W / 23.43778°N 0°E / 23.43778; 0 (Prime Meridian)
  The Tropic of Cancer, also referred to as the Northern tropic, is the circle of latitude on the Earth that marks the most northerly position at which the Sun may appear directly overhead at its zenith. This event occurs once per year, at the time of the June solstice, when the Northern Hemisphere is tilted toward the Sun to its maximum extent.
  Its Southern Hemisphere counterpart, marking the most southerly position at which the Sun may appear directly overhead, is the Tropic of Capricorn. These tropics are two of the five major degree measures or major circles of latitude that mark maps of the Earth, besides the Arctic and Antarctic Circles and the Equator. The positions of these circles of latitude (other than the Equator) are dictated by the tilt of the Earth's axis of rotation relative to the plane of its orbit.
  The imaginary line is called the Tropic of Cancer because when the Sun reaches the zenith at this latitude, it is entering the tropical sign of Cancer (summer solstice). When it was named, the Sun was also in the direction of the constellation Cancer (Latin for crab). However, this is no longer true due to the precession of the equinoxes. According to International Astronomical Union boundaries, the Sun now is in Taurus at the June solstice. According to sidereal astrology, which divides the zodiac into 12 equal parts, the Sun is in Gemini at that time. However, according to tropical astrology, which divides the ecliptic in twelve 30º sectors, starting with the vernal equinox, the Sun is always entering Cancer at this time, as the Earth's axial tilt is most inclined towards the Sun. The word "tropic" itself comes from the Greek τροπή (tropi), meaning turn, referring to the fact that the Sun appears to "turn back" at the solstices.

  The Tropic of Capricorn, or Southern tropic, marks the most southerly latitude on the Earth at which the Sun can be directly overhead. This event occurs at the December solstice, when the southern hemisphere is tilted towards the Sun to its maximum extent.
  The Tropic of Capricorn is one of the five major circles of latitude that mark maps of the Earth. It currently (Epoch 2012) lies 23° 26′ 16″ south of the Equator.
  It is currently drifting north at the rate of almost half a second (0.47″) of latitude, which is about 15 metres, per year (it was at exactly 23° 27' S in year 1917).
  The Tropic of Capricorn is the dividing line between the Southern Temperate Zone to the south and the tropics to the north. The northern hemisphere equivalent of the Tropic of Capricorn is the Tropic of Cancer.
  The position of the Tropic of Capricorn is not fixed, but rather it varies in a complex manner over time; see under circles of latitude for information.

  United Kingdom
  The United Kingdom of Great Britain and Northern Ireland (commonly known as the United Kingdom, the UK, or Britain) is a sovereign state located off the north-western coast of continental Europe. The country includes the island of Great Britain, the north-eastern part of the island of Ireland and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign state—the Republic of Ireland. Apart from this land border the UK is surrounded by the Atlantic Ocean, the North Sea, the English Channel and the Irish Sea.
  The United Kingdom is a unitary state governed under a constitutional monarchy and a parliamentary system, with its seat of government in the capital city of London. It is a country in its own right and consists of four countries: England, Northern Ireland, Scotland and Wales. There are three devolved administrations, each with varying powers, based in Belfast, Edinburgh and Cardiff, the capitals of Northern Ireland, Scotland, and Wales. Associated with the UK, but not constitutionally part of it, are three Crown Dependencies. The United Kingdom has fourteen overseas territories. These are remnants of the British Empire which, at its height in 1922, encompassed almost a quarter of the world's land surface and was the largest empire in history. British influence can still be observed in the language, culture and legal systems of many of its former territories.
