The Pacific Ocean is the largest and deepest of Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia in the west and the Americas in the east. At 165,250,000 square kilometers in area, this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about one-third of its total surface area, making it larger than all of Earth's land area combined; the centers of both the Water Hemisphere and the Western Hemisphere are in the Pacific Ocean. The equator subdivides it into the North Pacific Ocean and South Pacific Ocean, with two exceptions: the Galápagos and Gilbert Islands, while straddling the equator, are deemed wholly within the South Pacific, its mean depth is 4,000 meters. The Mariana Trench in the western North Pacific is the deepest point in the world, reaching a depth of 10,911 meters; the western Pacific has many peripheral seas. Though the peoples of Asia and Oceania have traveled the Pacific Ocean since prehistoric times, the eastern Pacific was first sighted by Europeans in the early 16th century when Spanish explorer Vasco Núñez de Balboa crossed the Isthmus of Panama in 1513 and discovered the great "southern sea" which he named Mar del Sur.
The ocean's current name was coined by Portuguese explorer Ferdinand Magellan during the Spanish circumnavigation of the world in 1521, as he encountered favorable winds on reaching the ocean. He called it Mar Pacífico, which in both Portuguese and Spanish means "peaceful sea". Important human migrations occurred in the Pacific in prehistoric times. About 3000 BC, the Austronesian peoples on the island of Taiwan mastered the art of long-distance canoe travel and spread themselves and their languages south to the Philippines and maritime Southeast Asia. Long-distance trade developed all along the coast from Mozambique to Japan. Trade, therefore knowledge, extended to the Indonesian islands but not Australia. By at least 878 when there was a significant Islamic settlement in Canton much of this trade was controlled by Arabs or Muslims. In 219 BC Xu Fu sailed out into the Pacific searching for the elixir of immortality. From 1404 to 1433 Zheng He led expeditions into the Indian Ocean; the first contact of European navigators with the western edge of the Pacific Ocean was made by the Portuguese expeditions of António de Abreu and Francisco Serrão, via the Lesser Sunda Islands, to the Maluku Islands, in 1512, with Jorge Álvares's expedition to southern China in 1513, both ordered by Afonso de Albuquerque from Malacca.
The east side of the ocean was discovered by Spanish explorer Vasco Núñez de Balboa in 1513 after his expedition crossed the Isthmus of Panama and reached a new ocean. He named it Mar del Sur because the ocean was to the south of the coast of the isthmus where he first observed the Pacific. In 1519, Portuguese explorer Ferdinand Magellan sailed the Pacific East to West on a Spanish expedition to the Spice Islands that would result in the first world circumnavigation. Magellan called the ocean Pacífico because, after sailing through the stormy seas off Cape Horn, the expedition found calm waters; the ocean was called the Sea of Magellan in his honor until the eighteenth century. Although Magellan himself died in the Philippines in 1521, Spanish Basque navigator Juan Sebastián Elcano led the remains of the expedition back to Spain across the Indian Ocean and round the Cape of Good Hope, completing the first world circumnavigation in a single expedition in 1522. Sailing around and east of the Moluccas, between 1525 and 1527, Portuguese expeditions discovered the Caroline Islands, the Aru Islands, Papua New Guinea.
In 1542–43 the Portuguese reached Japan. In 1564, five Spanish ships carrying 379 explorers crossed the ocean from Mexico led by Miguel López de Legazpi, sailed to the Philippines and Mariana Islands. For the remainder of the 16th century, Spanish influence was paramount, with ships sailing from Mexico and Peru across the Pacific Ocean to the Philippines via Guam, establishing the Spanish East Indies; the Manila galleons operated for two and a half centuries, linking Manila and Acapulco, in one of the longest trade routes in history. Spanish expeditions discovered Tuvalu, the Marquesas, the Cook Islands, the Solomon Islands, the Admiralty Islands in the South Pacific. In the quest for Terra Australis, Spanish explorations in the 17th century, such as the expedition led by the Portuguese navigator Pedro Fernandes de Queirós, discovered the Pitcairn and Vanuatu archipelagos, sailed the Torres Strait between Australia and New Guinea, named after navigator Luís Vaz de Torres. Dutch explorers, sailing around southern Africa engaged in discovery and trade.
In the 16th and 17th centuries Spain considered the Pacific Ocean a mare clausum—a sea closed to other naval powers. As the only known entrance from the Atlantic, the Strait of Magellan was at times patrolled by fleets sent to prevent entrance of non-Spanish ships. On the western side of the Pacific Ocean the Dutch threatened the Spanish Philippines; the 18th cen
Albania the Republic of Albania, is a country in Southeast Europe on the Adriatic and Ionian Sea within the Mediterranean Sea. It shares land borders with Montenegro to the northwest, Kosovo to the northeast, North Macedonia to the east, Greece to the south and a maritime border with Italy to the west. Geographically, the country displays varied climatic, geological and morphological conditions, defined in an area of 28,748 km2, it possesses remarkable diversity with the landscape ranging from the snow-capped mountains in the Albanian Alps as well as the Korab, Skanderbeg and Ceraunian Mountains to the hot and sunny coasts of the Albanian Adriatic and Ionian Sea along the Mediterranean Sea. The area of Albania was populated by various Illyrian and Ancient Greek tribes as well as several Greek colonies established in the Illyrian coast; the area was annexed in the 3rd century by Romans and became an integral part of the Roman provinces of Dalmatia and Illyricum. The autonomous Principality of Arbër emerged in 1190, established by archon Progon in the Krujë, within the Byzantine Empire.
In the late thirteenth century, Charles of Anjou conquered Albanian territories from the Byzantines and established the medieval Kingdom of Albania, which at its maximal extension was extending from Durrës along the coast to Butrint in the south. In the mid-fifteenth century, it was conquered by the Ottomans; the modern nation state of Albania emerged in 1912 following the defeat of the Ottomans in the Balkan Wars. The modern Kingdom of Albania was invaded by Italy in 1939, which formed Greater Albania, before becoming a Nazi German protectorate in 1943. After the defeat of Nazi Germany, a Communist state titled the People's Socialist Republic of Albania was founded under the leadership of Enver Hoxha and the Party of Labour; the country experienced widespread social and political transformations in the communist era, as well as isolation from much of the international community. In the aftermath of the Revolutions of 1991, the Socialist Republic was dissolved and the fourth Republic of Albania was established.
Politically, the country is a unitary parliamentary constitutional republic and developing country with an upper-middle income economy dominated by the tertiary sector followed by the secondary and primary sector. It went through a process of transition, following the end of communism in 1990, from a centralized to a market-based economy, it provides universal health care and free primary and secondary education to its citizens. The country is a member of the United Nations, World Bank, UNESCO, NATO, WTO, COE, OSCE and OIC, it is an official candidate for membership in the European Union. In addition it is one of the founding members of the Energy Community, including the Organization of the Black Sea Economic Cooperation and Union for the Mediterranean; the term Albania is the medieval Latin name of the country. It may be derived from the Illyrian tribe of Albani recorded by Ptolemy, the geographer and astronomer from Alexandria, who drafted a map in 150 AD, which shows the city of Albanopolis located northeast of the city of Durrës.
The term may have a continuation in the name of a medieval settlement called Albanon or Arbanon, although it is not certain that this was the same place. In his history written in the 10th century, the Byzantine historian Michael Attaliates was the first to refer to Albanoi as having taken part in a revolt against Constantinople in 1043 and to the Arbanitai as subjects of the Duke of Dyrrachium. During the Middle Ages, the Albanians called their country Arbëri or Arbëni and referred to themselves as Arbëreshë or Arbëneshë. Nowadays, Albanians call their country Shqipëria; as early as the 17th century the placename Shqipëria and the ethnic demonym Shqiptarë replaced Arbëria and Arbëresh. The two terms are popularly interpreted as "Land of the Eagles" and "Children of the Eagles"; the first traces of human presence in Albania, dating to the Middle Paleolithic and Upper Paleolithic eras, were found in the village of Xarrë close to Sarandë and Dajti near Tiranë. The objects found in a cave near Xarrë include flint and jasper objects and fossilized animal bones, while those found at Mount Dajt comprise bone and stone tools similar to those of the Aurignacian culture.
The Paleolithic finds of Albania show great similarities with objects of the same era found at Crvena Stijena in Montenegro and north-western Greece. Several Bronze Age artefacts from tumulus burials have been unearthed in central and southern Albania that show close connection with sites in south-western Macedonia and Lefkada, Greece. Archaeologists have come to the conclusion that these regions were inhabited from the middle of the third millennium BC by Indo-European people who spoke a Proto-Greek language. A part of this population moved to Mycenae around 1600 BC and founded the Mycenaean civilisation there. In ancient times, the territory of modern Albania was inhabited by a number of Illyrian tribes; the Illyrian tribes never collectively regarded themselves as'Illyrians', it is unlikely that they used any collective nomenclature for themselves. The name Illyrians seems to be the name applied to a specific Illyrian tribe, the first to come in contact with the ancient Greeks during the Bronze Age, causing the name Illyrians to be applied pars pro toto to all people of similar language and customs.
The territory known as Illyria corresponded to the area east of the Adriatic sea, extending in the south to the mouth of the Vjosë river. The first accou
Corsica is an island in the Mediterranean Sea and one of the 18 regions of France. It is located southeast of the French mainland and west of the Italian Peninsula, with the nearest land mass being the Italian island of Sardinia to the immediate south. A single chain of mountains makes up two-thirds of the island. While being part of Metropolitan France, Corsica is designated as a territorial collectivity by law; as a territorial collectivity, Corsica enjoys a greater degree of autonomy than other French regions. The island formed a single department until it was split in 1975 into two historical departments: Haute-Corse and Corse-du-Sud, with its regional capital in Ajaccio, the prefecture city of Corse-du-Sud. Bastia, the prefecture city of Haute-Corse, is the second largest settlement in Corsica; the two departments, the region of Corsica, merged again into a single territorial collectivity in 2018. After being ruled by the Republic of Genoa since 1284, Corsica was an Italian-speaking independent republic from 1755, until it was ceded by the Republic of Genoa to Louis XV as part of a pledge for debts and conquered in 1769.
Napoleon Bonaparte was born the same year in Ajaccio, his ancestral home, Maison Bonaparte, is today a significant visitor attraction and museum. Due to Corsica's historical ties with the Italian peninsula, the island retains to this day many Italian cultural elements: the native tongue is recognized as a regional language by the French government; the origin of the name Corsica remains a mystery. To the Ancient Greeks it was known as Kalliste, Cyrnos, Cernealis, or Cirné. Of these Cyrnos, Cernealis, or Cirné derive from the most ancient Greek name of the island, "Σειρηνούσσαι", the same Sirens mentioned in Homer's Odyssey. Corsica has been occupied continuously since the Mesolithic era, it acquired an indigenous population, influential in the Mediterranean during its long prehistory. After a brief occupation by the Carthaginians, colonization by the ancient Greeks, an only longer occupation by the Etruscans, it was incorporated by the Roman Republic at the end of the First Punic War and, with Sardinia, in 238 BC became a province of the Roman Republic.
The Romans, who built a colony in Aléria, considered Corsica as one of the most backward regions of the Roman world. The island produced sheep, honey and wax, exported many slaves, not well considered because of their fierce and rebellious character. Moreover, it was known for its cheap wines, exported to Rome, was used as a place of relegation, one of the most famous exiles being the Roman philosopher Seneca. Administratively, the island was divided in pagi, which in the Middle Ages became the pievi, the basic administrative units of the island until 1768. During the diffusion of Christianity, which arrived quite early from Rome and the Tuscan harbors, Corsica was home to many martyrs and saints: among them, the most important are Saint Devota and Saint Julia, both patrons of the island. Corsica was integrated into Roman Italy by Emperor Diocletian. In the 5th century, the western half of the Roman Empire collapsed, the island was invaded by the Vandals and the Ostrogoths. Recovered by the Byzantines, it soon became part of the Kingdom of the Lombards.
This made it a dependency of the March of Tuscany. Pepin the Short, king of the Franks and Charlemagne's father, expelled the Lombards and nominally granted Corsica to Pope Stephen II. In the first quarter of the 11th century and Genoa together freed the island from the threat of Arab invasion. After that, the island came under the influence of the republic of Pisa. To this period belong the many polychrome churches which adorn the island, Corsica experienced a massive immigration from Tuscany, which gave to the island its present toponymy and rendered the language spoken in the northern two-thirds of the island close to the Tuscan dialect. Due to that began the traditional division of Corsica in two parts, along the main chain of mountains going from Calvi to Porto-Vecchio: the eastern Banda di dentro, or Cismonte, more populated and open to the commerce with Italy, the western Banda di fuori, or Pomonte deserted and remote; the crushing defeat experienced by Pisa in 1284 in the Battle of Meloria against Genoa had among its consequences the end of the Pisan rule and the beginning of the Genoese influence in Corsica: this was contested by the King of Aragon, who in 1296 had received from the Pope the investiture over Sardinia and Corsica.
A popular revolution against this and the feudal lords, led by Sambucuccio d'Alando, got the aid of Genoa. After that, the Cismonte was ruled after the Italian experience; the following 150 years were a period of conflict, when the Genoese rule was contested by Aragon, the local lords, the comuni and the Pope: in 1450 Genoa ceded the administration of the island to its main bank, the Bank of Saint George, which brought peace. In the 16th century, the island entered into the fight between Spain and France for the supremacy in Italy. In 1553, a Franco-Ottoman fleet occupied Corsica, but the reaction of Spain and Genoa, led by Andrea Doria, reestablished the Genoese supremacy on the island, confirmed by the Peace of Cateau-Cambresis; the unlucky protagonist of this episode was Sampiero di Bastelica, who would come to be considered a hero of t
An equator of a rotating spheroid is its zeroth circle of latitude. It is the imaginary line on the spheroid, equidistant from its poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles. On Earth, the Equator is 21.3 % over land. Indonesia is the country straddling the greatest length of the equatorial line across both land and sea; the name is derived from medieval Latin word aequator, in the phrase circulus aequator diei et noctis, meaning ‘circle equalizing day and night’, from the Latin word aequare meaning ‘make equal’. The latitude of the Earth's equator is, by definition, 0° of arc; the Equator is one of the five notable circles of latitude on Earth. The Equator is the only line of latitude, a great circle — that is, one whose plane passes through the center of the globe; the plane of Earth's equator, when projected outwards to the celestial sphere, defines the celestial equator.
In the cycle of Earth's seasons, the equatorial plane runs through the Sun twice per year: on the equinoxes in March and September. To a person on Earth, the Sun appears to travel above the Equator at these times. Light rays from the Sun's center are perpendicular to Earth's surface at the point of solar noon on the Equator. Locations on the Equator experience the shortest sunrises and sunsets because the Sun's daily path is nearly perpendicular to the horizon for most of the year; the length of daylight is constant throughout the year. Earth bulges at the Equator. Sites near the Equator, such as the Guiana Space Centre in Kourou, French Guiana, are good locations for spaceports as they have a faster rotational speed than other latitudes. Since Earth rotates eastward, spacecraft must be launched eastward to take advantage of this Earth-boost of speed; the precise location of the Equator is not fixed. This effect must be accounted for in detailed geophysical measurements; the International Association of Geodesy and the International Astronomical Union have chosen to use an equatorial radius of 6,378.1366 kilometres.
This equatorial radius is in the 2003 and 2010 IERS Conventions. It is the equatorial radius used for the IERS 2003 ellipsoid. If it were circular, the length of the Equator would be 2π times the radius, namely 40,075.0142 kilometres. The GRS 80 as approved and adopted by the IUGG at its Canberra, Australia meeting of 1979 has an equatorial radius of 6,378.137 kilometres. The WGS 84, a standard for use in cartography and satellite navigation including GPS has an equatorial radius of 6,378.137 kilometres. For both GRS 80 and WGS 84, this results in a length for the Equator of 40,075.0167 km. The geographical mile is defined as one arc-minute of the Equator, so it has different values depending on which radius is assumed. For example, by WSG-84, the distance is 1,855.3248 metres, while by IAU-2000, it is 1,855.3257 metres. This is a difference of less than one millimetre over the total distance; the earth is modeled as a sphere flattened 0.336% along its axis. This makes the Equator 0.16% longer than a meridian.
The IUGG standard meridian is, to the nearest millimetre, 40,007.862917 kilometres, one arc-minute of, 1,852.216 metres, explaining the SI standardization of the nautical mile as 1,852 metres, more than 3 metres less than the geographical mile. The sea-level surface of the Earth is irregular, so the actual length of the Equator is not so easy to determine. Aviation Week and Space Technology on 9 October 1961 reported that measurements using the Transit IV-A satellite had shown the equatorial "diameter" from longitude 11° West to 169° East to be 1,000 feet greater than its "diameter" ninety degrees away; the Equator passes through the land of 11 countries. Starting at the Prime Meridian and heading eastwards, the Equator passes through: Despite its name, no part of Equatorial Guinea lies on the Equator. However, its island of Annobón is 155 km south of the Equator, the rest of the country lies to the north. Seasons result from the tilt of the Earth's axis compared to the plane of its revolution around the Sun.
Throughout the year the northern and southern hemispheres are alternately turned either toward or away from the sun depending on Earth's position in its orbit. The hemisphere turned toward the sun receives more sunlight and is in summer, while the other hemisphere receives less sun and is in winter. At the equinoxes, the Earth's axis
China the People's Republic of China, is a country in East Asia and the world's most populous country, with a population of around 1.404 billion. Covering 9,600,000 square kilometers, it is the third- or fourth-largest country by total area. Governed by the Communist Party of China, the state exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities, the special administrative regions of Hong Kong and Macau. China emerged as one of the world's earliest civilizations, in the fertile basin of the Yellow River in the North China Plain. For millennia, China's political system was based on hereditary monarchies, or dynasties, beginning with the semi-legendary Xia dynasty in 21st century BCE. Since China has expanded, re-unified numerous times. In the 3rd century BCE, the Qin established the first Chinese empire; the succeeding Han dynasty, which ruled from 206 BC until 220 AD, saw some of the most advanced technology at that time, including papermaking and the compass, along with agricultural and medical improvements.
The invention of gunpowder and movable type in the Tang dynasty and Northern Song completed the Four Great Inventions. Tang culture spread in Asia, as the new Silk Route brought traders to as far as Mesopotamia and Horn of Africa. Dynastic rule ended in 1912 with the Xinhai Revolution; the Chinese Civil War resulted in a division of territory in 1949, when the Communist Party of China established the People's Republic of China, a unitary one-party sovereign state on Mainland China, while the Kuomintang-led government retreated to the island of Taiwan. The political status of Taiwan remains disputed. Since the introduction of economic reforms in 1978, China's economy has been one of the world's fastest-growing with annual growth rates above 6 percent. According to the World Bank, China's GDP grew from $150 billion in 1978 to $12.24 trillion by 2017. Since 2010, China has been the world's second-largest economy by nominal GDP and since 2014, the largest economy in the world by purchasing power parity.
China is the world's largest exporter and second-largest importer of goods. China is a recognized nuclear weapons state and has the world's largest standing army and second-largest defense budget; the PRC is a permanent member of the United Nations Security Council as it replaced the ROC in 1971, as well as an active global partner of ASEAN Plus mechanism. China is a leading member of numerous formal and informal multilateral organizations, including the Shanghai Cooperation Organization, WTO, APEC, BRICS, the BCIM, the G20. In recent times, scholars have argued that it will soon be a world superpower, rivaling the United States; the word "China" has been used in English since the 16th century. It is not a word used by the Chinese themselves, it has been traced through Portuguese and Persian back to the Sanskrit word Cīna, used in ancient India."China" appears in Richard Eden's 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. Barbosa's usage was derived from Persian Chīn, in turn derived from Sanskrit Cīna.
Cīna was first used including the Mahābhārata and the Laws of Manu. In 1655, Martino Martini suggested that the word China is derived from the name of the Qin dynasty. Although this derivation is still given in various sources, it is complicated by the fact that the Sanskrit word appears in pre-Qin literature; the word may have referred to a state such as Yelang. The meaning transferred to China as a whole; the origin of the Sanskrit word is still a matter of debate, according to the Oxford English Dictionary. The official name of the modern state is the "People's Republic of China"; the shorter form is "China" Zhōngguó, from zhōng and guó, a term which developed under the Western Zhou dynasty in reference to its royal demesne. It was applied to the area around Luoyi during the Eastern Zhou and to China's Central Plain before being used as an occasional synonym for the state under the Qing, it was used as a cultural concept to distinguish the Huaxia people from perceived "barbarians". The name Zhongguo is translated as "Middle Kingdom" in English.
Archaeological evidence suggests that early hominids inhabited China between 2.24 million and 250,000 years ago. The hominid fossils of Peking Man, a Homo erectus who used fire, were discovered in a cave at Zhoukoudian near Beijing; the fossilized teeth of Homo sapiens have been discovered in Fuyan Cave in Hunan. Chinese proto-writing existed in Jiahu around 7000 BCE, Damaidi around 6000 BCE, Dadiwan from 5800–5400 BCE, Banpo dating from the 5th millennium BCE; some scholars have suggested. According to Chinese tradition, the first dynasty was the Xia, which emerged around 2100 BCE; the dynasty was considered mythical by historians until scientific excavations found early Bronze Age sites at Erlitou, Henan in 1959. It remains unclear whether these sites are the remains of the Xia dynasty or of another culture from the same period; the succeeding Shang dynasty is the earliest to be confirmed by contemporary records. The Shang ruled the plain of the Yellow River in eastern China from the 17th to the 11th century BCE.

North America is a continent within the Northern Hemisphere and all within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, to the southeast by South America and the Caribbean Sea. North America covers an area of about 24,709,000 square kilometers, about 16.5% of the earth's land area and about 4.8% of its total surface. North America is the third largest continent by area, following Asia and Africa, the fourth by population after Asia and Europe. In 2013, its population was estimated at nearly 579 million people in 23 independent states, or about 7.5% of the world's population, if nearby islands are included. North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge 40,000 to 17,000 years ago; the so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago. The Classic stage spans the 6th to 13th centuries.
The Pre-Columbian era ended in 1492, the transatlantic migrations—the arrival of European settlers during the Age of Discovery and the Early Modern period. Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples, African slaves and their descendants. Owing to the European colonization of the Americas, most North Americans speak English, Spanish or French, their culture reflects Western traditions; the Americas are accepted as having been named after the Italian explorer Amerigo Vespucci by the German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies, but a different landmass unknown by Europeans. In 1507, Waldseemüller produced a world map, in which he placed the word "America" on the continent of South America, in the middle of what is today Brazil, he explained the rationale for the name in the accompanying book Cosmographiae Introductio:... ab Americo inventore... quasi Americi terram sive Americam.
For Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespucci's name, but in its feminine form "America", following the examples of "Europa", "Asia" and "Africa". Other mapmakers extended the name America to the northern continent, In 1538, Gerard Mercator used America on his map of the world for all the Western Hemisphere; some argue that because the convention is to use the surname for naming discoveries, the derivation from "Amerigo Vespucci" could be put in question. In 1874, Thomas Belt proposed a derivation from the Amerrique mountains of Central America. Marcou corresponded with Augustus Le Plongeon, who wrote: "The name AMERICA or AMERRIQUE in the Mayan language means, a country of perpetually strong wind, or the Land of the Wind, and... the can mean... a spirit that breathes, life itself." The United Nations formally recognizes "North America" as comprising three areas: Northern America, Central America, The Caribbean.
This has been formally defined by the UN Statistics Division. The term North America maintains various definitions in accordance with context. In Canadian English, North America refers to the land mass as a whole consisting of Mexico, the United States, Canada, although it is ambiguous which other countries are included, is defined by context. In the United States of America, usage of the term may refer only to Canada and the US, sometimes includes Greenland and Mexico, as well as offshore islands. In France, Portugal, Romania and the countries of Latin America, the cognates of North America designate a subcontinent of the Americas comprising Canada, the United States, Mexico, Greenland, Saint Pierre et Miquelon, Bermuda. North America has been referred to by other names. Spanish North America was referred to as Northern America, this was the first official name given to Mexico. Geographically the North American continent has many subregions; these include cultural and geographic regions. Economic regions included those formed by trade blocs, such as the North American Trade Agreement bloc and Central American Trade Agreement.
Linguistically and culturally, the continent could be divided into Latin America. Anglo-America includes most of Northern America and Caribbean islands with English-speaking populations; the southern North American continent is composed of two regions. These are the Caribbean; the north of the continent maintains recognized regions as well. In contrast to the common definition of "North America", which encompasses the whole continent, the term "North America" is sometimes used to refer only to Mexico, the United States, Greenland; the term Northern America refers to the northern-most countries and territories of North America: the United States, Bermuda, St. Pierre and Miquelon and Greenland. Although the term does not refer to a unifie
Europe is a continent located in the Northern Hemisphere and in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west and the Mediterranean Sea to the south, it comprises the westernmost part of Eurasia. Since around 1850, Europe is most considered to be separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas and the waterways of the Turkish Straits. Although the term "continent" implies physical geography, the land border is somewhat arbitrary and has been redefined several times since its first conception in classical antiquity; the division of Eurasia into two continents reflects East-West cultural and ethnic differences which vary on a spectrum rather than with a sharp dividing line. The geographic border does not follow political boundaries, with Turkey and Kazakhstan being transcontinental countries. A strict application of the Caucasus Mountains boundary places two comparatively small countries and Georgia, in both continents.
Europe covers 2 % of the Earth's surface. Politically, Europe is divided into about fifty sovereign states of which the Russian Federation is the largest and most populous, spanning 39% of the continent and comprising 15% of its population. Europe had a total population of about 741 million as of 2016; the European climate is affected by warm Atlantic currents that temper winters and summers on much of the continent at latitudes along which the climate in Asia and North America is severe. Further from the sea, seasonal differences are more noticeable than close to the coast. Europe, in particular ancient Greece, was the birthplace of Western civilization; the fall of the Western Roman Empire in 476 AD and the subsequent Migration Period marked the end of ancient history and the beginning of the Middle Ages. Renaissance humanism, exploration and science led to the modern era. Since the Age of Discovery started by Portugal and Spain, Europe played a predominant role in global affairs. Between the 16th and 20th centuries, European powers controlled at various times the Americas all of Africa and Oceania and the majority of Asia.
The Age of Enlightenment, the subsequent French Revolution and the Napoleonic Wars shaped the continent culturally and economically from the end of the 17th century until the first half of the 19th century. The Industrial Revolution, which began in Great Britain at the end of the 18th century, gave rise to radical economic and social change in Western Europe and the wider world. Both world wars took place for the most part in Europe, contributing to a decline in Western European dominance in world affairs by the mid-20th century as the Soviet Union and the United States took prominence. During the Cold War, Europe was divided along the Iron Curtain between NATO in the West and the Warsaw Pact in the East, until the revolutions of 1989 and fall of the Berlin Wall. In 1949 the Council of Europe was founded, following a speech by Sir Winston Churchill, with the idea of unifying Europe to achieve common goals, it includes all European states except for Belarus and Vatican City. Further European integration by some states led to the formation of the European Union, a separate political entity that lies between a confederation and a federation.
The EU originated in Western Europe but has been expanding eastward since the fall of the Soviet Union in 1991. The currency of most countries of the European Union, the euro, is the most used among Europeans. In classical Greek mythology, Europa was a Phoenician princess; the word Europe is derived from her name. The name contains the elements εὐρύς, "wide, broad" and ὤψ "eye, countenance", hence their composite Eurṓpē would mean "wide-gazing" or "broad of aspect". Broad has been an epithet of Earth herself in the reconstructed Proto-Indo-European religion and the poetry devoted to it. There have been attempts to connect Eurṓpē to a Semitic term for "west", this being either Akkadian erebu meaning "to go down, set" or Phoenician'ereb "evening, west", at the origin of Arabic Maghreb and Hebrew ma'arav. Michael A. Barry, professor in Princeton University's Near Eastern Studies Department, finds the mention of the word Ereb on an Assyrian stele with the meaning of "night, sunset", in opposition to Asu " sunrise", i.e. Asia.
The same naming motive according to "cartographic convention" appears in Greek Ἀνατολή. Martin Litchfield West stated that "phonologically, the match between Europa's name and any form of the Semitic word is poor."
