A convention influences a set of agreed, stipulated, or generally accepted standards, social norms , or other criteria, often taking the form of a custom.
125-903: A continent is any of several large geographical regions. Continents are generally identified by convention rather than any strict criteria. A continent could be a single landmass or a part of a very large landmass, as in the case of Asia or Europe. Due to this, the number of continents varies; up to seven or as few as four geographical regions are commonly regarded as continents. Most English-speaking countries recognize seven regions as continents. In order from largest to smallest in area, these seven regions are Asia , Africa , North America , South America , Antarctica , Europe , and Australia . Different variations with fewer continents merge some of these regions; examples of this are merging North America and South America into America , Asia and Europe into Eurasia , and Africa, Asia, and Europe into Afro-Eurasia . Oceanic islands are occasionally grouped with
250-646: A maritime border , to the west and southwest across Nares Strait and Baffin Bay, as well as a shared land border on Hans Island ; and Iceland, southeast of Greenland in the Atlantic Ocean. Greenland also contains the world's largest national park , and it is the largest constituent country by area in the world, and is the fourth largest country subdivision in the world , after Sakha Republic in Russia, Australia's state of Western Australia , and Russia's Krasnoyarsk Krai , and
375-468: A series of expeditions to Greenland and Arctic waterways to locate the lost eastern Norse settlement and assert Danish-Norwegian sovereignty over Greenland. The expeditions were mostly unsuccessful, partly due to leaders who lacked experience with the difficult Arctic ice and weather conditions, and partly because the expedition leaders were given instructions to search for the Eastern Settlement on
500-572: A continent as "a large space of dry land comprehending many countries all joined together, without any separation by water. Thus Europe, Asia, and Africa is one great continent, as America is another." However, the old idea of Europe, Asia and Africa as "parts" of the world ultimately persisted with these being regarded as separate continents. By convention, continents "are understood to be large, continuous, discrete masses of land, ideally separated by expanses of water". In modern schemes with five or more recognized continents, at least one pair of continents
625-518: A continent. This divides the entire land surface of Earth into continents, regions, or quasi-continents. The criterion that each continent is a discrete landmass is commonly relaxed due to historical conventions and practical use. Of the seven most globally recognized continents, only Antarctica and Australia are completely separated from other continents by the ocean. Several continents are defined not as absolutely distinct bodies but as " more or less discrete masses of land". Africa and Asia are joined by
750-602: A discrete landmass is completely disregarded if the continuous landmass of Eurasia is classified as two separate continents (Asia and Europe). Physiographically , Europe and the Indian subcontinent are large peninsulas of the Eurasian landmass. However, Europe is considered a continent with its comparatively large land area of 10,180,000 square kilometres (3,930,000 sq mi), while the Indian subcontinent, with less than half that area,
875-421: A geological continent has been disputed by some geologists. However, a study conducted in 2021 found that part of the submerged continent is indeed Precambrian , twice as old as geologists had previously thought, which is further evidence that supports the idea of Zealandia being a geological continent. All seven geological continents are spatially isolated by geologic features. The term "continent" translates
1000-525: A measured property of nature, but originate in a convention, for example an average of many measurements, agreed between the scientists working with these values. A convention is a selection from among two or more alternatives, where the rule or alternative is agreed upon among participants. Often the word refers to unwritten customs shared throughout a community. For instance, it is conventional in many societies that strangers being introduced shake hands. Some conventions are explicitly legislated; for example, it
1125-541: A nearby continent to divide all the world's land into geographical regions. Under this scheme, most of the island countries and territories in the Pacific Ocean are grouped together with the continent of Australia to form the geographical region Oceania . In geology , a continent is defined as "one of Earth's major landmasses, including both dry land and continental shelves ". The geological continents correspond to seven large areas of continental crust that are found on
1250-480: A number lost their cultural ties to Greenland. While the policies "succeeded" in the sense of shifting Greenlanders from being primarily subsistence hunters into being urbanized wage earners, the Greenlandic elite began to reassert a Greenlandic cultural identity. A movement developed in favour of independence, reaching its peak in the 1970s. As a consequence of political complications in relation to Denmark's entry into
1375-423: A number of governmental services and areas of competence. The Danish government retains control of citizenship, monetary policy, and foreign affairs, including defence. Most residents of Greenland are Inuit. The population is concentrated mainly on the southwest coast, and the rest of the island is sparsely populated. Three-quarters of Greenland is covered by the only permanent ice sheet outside Antarctica . With

Sixty-seven percent of its electricity production comes from renewable energy, mostly from hydropower . The early Norse settlers named the island Greenland . In the Icelandic sagas , the Norwegian Erik the Red was exiled from Iceland with his father, Thorvald, who had committed manslaughter. With his extended family and his thralls ( slaves or serfs ) , he set out in ships to explore an icy land known to lie to

Barley was grown as a crop up to the 70th parallel. The ice cores show that Greenland has had dramatic temperature shifts many times in the past 100,000 years. Similarly the Icelandic Book of Settlements records famines during

Greenland's goal for returning tourism is to develop it "right" and to "build a more sustainable tourism for the long run". Greenland is the world's largest non-continental island and
1875-458: A sense of self-reliance through self-government and independent communication with the outside world. Despite this change, in 1946 a commission including the highest Greenlandic council, the Landsrådene , recommended patience and no radical reform of the system. Two years later, the first step towards a change of government was initiated when a grand commission was established. A final report (G-50)
2000-510: A separate land. In 1507 Martin Waldseemüller published a world map, Universalis Cosmographia , which was the first to show North and South America as separate from Asia and surrounded by water. A small inset map above the main map explicitly showed for the first time the Americas being east of Asia and separated from Asia by an ocean, as opposed to just placing the Americas on the left end of
2125-403: A separate people under international law . Denmark maintains control of foreign affairs and defence matters. Denmark upholds the annual block grant of 3.2 billion Danish kroner, but as Greenland begins to collect revenues of its natural resources, the grant will gradually be diminished. This is generally considered to be a step toward eventual full independence from Denmark. Greenlandic
2250-453: A social rule changes over time within the same society. What was acceptable in the past may no longer be the case. Similarly, rules differ across space: what is acceptable in one society may not be so in another. Social rules reflect what is acceptable or normal behaviour in any situation. Michel Foucault 's concept of discourse is closely related to social rules as it offers a possible explanation how these rules are shaped and change. It
2375-405: A society, but at the same time, are re-produced by the individuals. Sociologists representing symbolic interactionism argue that social rules are created through the interaction between the members of a society. The focus on active interaction highlights the fluid, shifting character of social rules. These are specific to the social context, a context that varies through time and place. That means
2500-789: A third part of the world. Division into three parts eventually came to predominate. From the Greek viewpoint, the Aegean Sea was the center of the world; Asia lay to the east, Europe to the north and west, and Africa to the south. The boundaries between the continents were not fixed. Early on, the Europe–Asia boundary was taken to run from the Black Sea along the Rioni River (known then as the Phasis ) in Georgia . Later it
2625-495: A very large peninsula on the fringe of a continent. Where the Americas are viewed as a single continent (America), it is divided into two subcontinents ( North America and South America ) or three ( Central America being the third). When Eurasia is regarded as a single continent, Asia and Europe are treated as subcontinents. Some areas of continental crust are largely covered by the ocean and may be considered submerged continents . Notable examples are Zealandia , emerging from

It is the larger of two autonomous territories within the Kingdom, the other being the Faroe Islands ; the citizens of both territories are full citizens of Denmark . As Greenland is one of the Overseas Countries and Territories of the European Union , citizens of Greenland are European Union citizens . The capital and largest city of Greenland
3250-450: Is considered a subcontinent. The alternative view—in geology and geography—that Eurasia is a single continent results in a six-continent view of the world. Some view the separation of Eurasia into Asia and Europe as a residue of Eurocentrism : "In physical, cultural and historical diversity, China and India are comparable to the entire European landmass, not to a single European country. [...]." However, for historical and cultural reasons,

The standardization of time is a human convention based on the solar cycle or calendar. The extent to which justice is conventional (as opposed to natural or objective ) is historically an important debate among philosophers . The nature of conventions has raised long-lasting philosophical discussion. Quine , Davidson , and David Lewis published influential writings on

The geological definition of a continent has four criteria: high elevation relative to the ocean floor; a wide range of igneous, metamorphic and sedimentary rocks rich in silica; a crust thicker than the surrounding oceanic crust; and well-defined limits around a large enough area. The most restricted meaning of continent

Within a few years, the name "New World" began appearing as a name for South America on world maps, such as the Oliveriana (Pesaro) map of around 1504–1505. Maps of this time, though, still showed North America connected to Asia and showed South America as

The criterion "large" leads to arbitrary classification: Greenland , with a surface area of 2,166,086 square kilometres (836,330 sq mi), is only considered the world's largest island, while Australia , at 7,617,930 square kilometres (2,941,300 sq mi), is deemed the smallest continent.

[it has] one centre, where an immense mountain – Mount Meru (or Maha Meru, Great Meru) – stands ... The continents encircle the mountain in seven concentric circles ... It seems clear that the Himalayas were the approximate location of Mt. Meru and the text is clear that the earth has seven continents. Convention (norm) In physical sciences , numerical values (such as constants, quantities, or scales of measurement) are called conventional if they do not represent
9375-467: The east coast of Greenland just north of Cape Farewell , which is almost inaccessible due to southward drifting ice . The pilot on all three trips was English explorer James Hall . After the Norse settlements died off, Greenland came under the de facto control of various Inuit groups, but the Dano-Norwegian government never forgot or relinquished the claims to Greenland that it had inherited from
9500-589: The eighth continent. The following table provides areas given by Encyclopædia Britannica for each continent in accordance with the seven-continent model, including Australasia along with Melanesia , Micronesia , and Polynesia as parts of Oceania. It also provides populations of continents according to 2021 estimates by the United Nations Statistics Division based on the United Nations geoscheme , which includes all of Egypt (including
9625-568: The existence of a new island was announced. Named " Uunartoq Qeqertaq " (English: Warming Island ), this island has always been present off the coast of Greenland, but was covered by a glacier. This glacier was discovered in 2002 to be shrinking rapidly, and by 2007 had completely melted away, leaving the exposed island. The island was named Place of the Year by the Oxford Atlas of the World in 2007. Ben Keene,
9750-606: The facilities. After the collapse of the Third Reich, Albert Speer briefly considered escaping in a small aeroplane to hide out in Greenland, but changed his mind and decided to surrender to the United States Armed Forces . Greenland had been a protected and very isolated society until 1940. The Danish government had maintained a strict monopoly of Greenlandic trade , allowing no more than small scale barter trading with British whalers. In wartime Greenland developed
9875-447: The global sea levels would increase by ~7.4 m (24 ft) from that alone. However, it also means that it will take at least 1,000 years for the ice sheet to disappear even with very high warming, and in around 10,000 years under lower warming which still crosses the threshold for the ice sheet's disappearance. This threshold likely lies for the global warming between 1.7 °C (3.1 °F) and 2.3 °C (4.1 °F). Reducing
10000-405: The history of the island, specifically over whether the island might have been revealed during a brief warm period in Greenland during the mid-20th century. Greenland ice sheet always loses some mass from ice calving at its coasts, but it used to gain more ice on average due to the accumulation of snowfall. Yet, Greenland has been warming starting from around 1900, and starting from 1980s,
10125-422: The ice sheet, Greenland is composed of three large islands. This is disputed, but if it is so, they would be separated by narrow straits, reaching the sea at Ilulissat Icefjord , at Greenland's Grand Canyon and south of Nordostrundingen . All towns and settlements of Greenland are situated along the ice-free coast, with the population being concentrated along the west coast. The northeastern part of Greenland
10250-402: The ice sheet, established in 1989. The radio station Jørgen Brønlund Fjord was, until 1950, the northernmost permanent outpost in the world. The extreme north of Greenland, Peary Land , is not covered by an ice sheet, because the air there is too dry to produce snow, which is essential in the production and maintenance of an ice sheet. If the Greenland ice sheet were to melt away completely,
10375-583: The largest in North America. The lowest temperature ever recorded in the Northern Hemisphere was recorded in Greenland, near the topographic summit of the Greenland Ice Sheet , on 22 December 1991, when the temperature reached −69.6 °C (−93.3 °F). In Nuuk, the average daily temperature varies over the seasons from −5.1 to 9.9 °C (22.8 to 49.8 °F). The total area of Greenland
10500-479: The losses became larger than the gains. After 1996, Greenland has not had a single year when it did not lose mass on average. In 2010s, Greenland ice sheet had been melting at its fastest rate over at least the past 12,000 years, and on track to exceed that later in the century. In 2012, 2019 and 2021, so-called "massive melting events" had occurred, when practically the entire surface of the ice sheet had been melting and no accumulation had been taking place. During
10625-427: The map and Asia on the right end. In the accompanying book Cosmographiae Introductio , Waldseemüller noted that the earth is divided into four parts, Europe, Asia, Africa, and the fourth part, which he named "America" after Amerigo Vespucci's first name. On the map, the word "America" was placed on part of South America. The Sanskrit text Rig Veda often dated 1500 BCE has the earliest mention of seven continents in
10750-491: The mid-17th century, Peter Heylin wrote in his Cosmographie that "A Continent is a great quantity of Land, not separated by any Sea from the rest of the World, as the whole Continent of Europe, Asia, Africa." In 1727, Ephraim Chambers wrote in his Cyclopædia, "The world is ordinarily divided into two grand continents: the Old and the New ." And in his 1752 atlas, Emanuel Bowen defined
10875-417: The mission there and returned to Denmark, where he established a Greenland Seminary. This new colony was centred at Godthåb ("Good Hope") on the southwest coast. Gradually, Greenland was opened up to Danish merchants, but closed to those from other countries. When the union between the crowns of Denmark and Norway was dissolved in 1814, the Treaty of Kiel severed Norway's former colonies and left them under
11000-528: The most beauteous portion of the earth. Indeed, many persons have, not without reason, considered it, not as a third part only of the earth, but as equal to all the rest, looking upon the whole of our globe as divided into two parts only, by a line drawn from the river Tanais to the Straits of Gades. Following the fall of the Western Roman Empire , the culture that developed in its place , linked to Latin and
11125-411: The northwest. After finding a habitable area and settling there, he named it Grœnland (translated as "Greenland"), supposedly in the hope that the pleasant name would attract settlers. The Saga of Erik the Red states: "In the summer, Erik left to settle in the country he had found, which he called Greenland, as he said people would be attracted there if it had a favorable name." The name of
11250-466: The ocean primarily in New Zealand and New Caledonia , and the almost completely submerged Kerguelen Plateau in the southern Indian Ocean . Some islands lie on sections of continental crust that have rifted and drifted apart from a main continental landmass. While not considered continents because of their relatively small size, they may be considered microcontinents . Madagascar, the largest example,
11375-507: The only contemporary records or historiography that survives from the Norse settlements is of their contact with Iceland or Norway. Medieval Norwegian sagas and historical works mention Greenland's economy, the bishops of Gardar , and the collection of tithes. A chapter in the Konungs skuggsjá ( The King's Mirror ) describes Norse Greenland 's exports, imports, and grain cultivation. Icelandic saga accounts of life in Greenland were composed in
11500-451: The others together, and it appears to me to be wider beyond all comparison. Eratosthenes , in the 3rd century BCE, noted that some geographers divided the continents by rivers (the Nile and the Don), thus considering them "islands". Others divided the continents by isthmuses , calling the continents "peninsulas". These latter geographers set the border between Europe and Asia at the isthmus between
11625-481: The people in Greenland citizens of Denmark. In the 1979 Greenlandic home rule referendum , Denmark granted home rule to Greenland; in the 2008 Greenlandic self-government referendum , Greenlanders voted for the Self-Government Act, which transferred more power from the Danish government to the local Naalakkersuisut (Greenlandic government). Under this structure, Greenland gradually assumed responsibility for
11750-474: The place whence Vishnu strode Through the seven regions of the earth! Through all this world strode Vishnu; thrice his foot he planted, and the whole Was gathered in his footstep's dust. Vishnu, the Guardian, he whom none deceiveth , made three steps; thenceforth Establishing his high decrees. In regard to the above-quoted verses, it is commonly accepted that there are Seven Continents or 'regions of
11875-485: The present continents. Certain parts of continents are recognized as subcontinents, especially the large peninsulas separated from the main continental landmass by geographical features. The most widely recognized example is the Indian subcontinent . The Arabian Peninsula , Southern Africa , the Southern Cone of South America, and Alaska in North America might be considered further examples. In many of these cases,
12000-568: The sea frozen, they headed south and arrived in Labrador and Newfoundland . Upon the brothers' return to Portugal, the cartographic information supplied by Corte-Real was incorporated into a new map of the world which was presented to Ercole I d'Este , Duke of Ferrara , by Alberto Cantino in 1502. The Cantino planisphere , made in Lisbon, accurately depicts the southern coastline of Greenland. In 1605–1607, King Christian IV of Denmark and Norway sent
12125-541: The seven-continent model. However, they may also be viewed as a single continent known as America . This viewpoint was common in the United States until World War II , and remains prevalent in some Asian six-continent models. The single American continent model remains a common view in European countries like France, Greece, Hungary, Italy, Malta, Portugal, Spain, Latin American countries and some Asian countries. The criterion of
12250-413: The shelf ( continental islands ), as they are structurally part of the continent. From this perspective, the edge of the continental shelf is the true edge of the continent, as shorelines vary with changes in sea level. In this sense the islands of Great Britain and Ireland are part of Europe, while Australia and the island of New Guinea together form a continent. Taken to its limit, this view could support
12375-442: The statement, "Greenland is not for sale and cannot be sold, but Greenland is open for trade and cooperation with other countries—including the United States." In 1950, Denmark agreed to allow the US to regain the use of Thule Air Base ; it was greatly expanded between 1951 and 1953 as part of a unified NATO Cold War defence strategy. The local population of three nearby villages was moved more than 100 km (62 miles) away in
12500-811: The subject. Lewis's account of convention received an extended critique in Margaret Gilbert 's On Social Facts (1989), where an alternative account is offered. Another view of convention comes from Ruth Millikan 's Language: A Biological Model (2005), once more against Lewis. According to David Kalupahana, The Buddha described conventions—whether linguistic, social, political, moral, ethical, or even religious—as arising dependent on specific conditions. According to his paradigm, when conventions are considered absolute realities, they contribute to dogmatism, which in turn leads to conflict. This does not mean that conventions should be absolutely ignored as unreal and therefore useless. Instead, according to Buddhist thought,
12625-451: The system of government changed: Governor Eske Brun ruled the island under a law of 1925 that allowed governors to take control under extreme circumstances; Governor Aksel Svane was transferred to the United States to lead the commission to supply Greenland. The Danish Sirius Patrol guarded the northeastern shores of Greenland in 1942 using dog sleds. They detected several German weather stations and alerted American troops, who destroyed
12750-658: The territory in the Greenlandic language is Kalaallit Nunaat ' land of the Kalaallit ' . The Kalaallit are the Greenlandic Inuit who inhabit the territory's western region. In prehistoric times, Greenland was home to several successive Paleo-Inuit cultures known primarily through archaeological finds. The earliest entry of the Paleo-Inuit into Greenland is thought to have occurred about 2500 BC. From about 2500 BC to 800 BC, southern and western Greenland
12875-753: The third largest area in North America after Canada and the United States. It is between latitudes 59° and 83°N , and longitudes 11° and 74°W . Greenland is bordered by the Arctic Ocean to the north, the Greenland Sea to the east, the North Atlantic Ocean to the southeast, the Davis Strait to the southwest, Baffin Bay to the west, the Nares Strait and Lincoln Sea to the northwest. The nearest countries to Greenland are Canada, with which it shares
13000-625: The three continents. By the middle of the 18th century, "the fashion of dividing Asia and Africa at the Nile, or at the Great Catabathmus [the boundary between Egypt and Libya ] farther west, had even then scarcely passed away". Christopher Columbus sailed across the Atlantic Ocean to the Caribbean in 1492, sparking a period of European exploration of the Americas . But despite four voyages to
13125-486: The traditional doctrine (Dicey) , conventions cannot be enforced in courts, because they are non-legal sets of rules. Convention is particularly important in the Westminster System of government, where many of the rules are unwritten. Greenland Greenland ( Greenlandic : Kalaallit Nunaat , pronounced [kalaːɬːit nʉnaːt] ; Danish : Grønland , pronounced [ˈkʁɶnˌlænˀ] )
13250-427: The turn of the 14th century—as much as 6 to 8 °C (11 to 14 °F) lower than modern summer temperatures. The study also found that the lowest winter temperatures of the last 2,000 years occurred in the late 14th century and early 15th century. The Eastern Settlement was probably abandoned in the early to mid-15th century, during this cold period . Theories drawn from archeological excavations at Herjolfsnes in
13375-486: The uninhabited southern part of Greenland beginning in the 10th century (having previously settled Iceland ), and the 13th century saw the arrival of Inuit . In the early 17th century, Dano-Norwegian explorers reached Greenland again. When Denmark and Norway separated in 1814, Greenland was transferred to the Danish crown, and was fully integrated in the Danish state in 1953 under the Constitution of Denmark , which made
13500-478: The view of Europe as a separate continent continues in almost all categorizations. If continents are defined strictly as discrete landmasses, embracing all the contiguous land of a body, then Africa, Asia, and Europe form a single continent which may be referred to as Afro-Eurasia . Combined with the consolidation of the Americas, this would produce a four-continent model consisting of Afro-Eurasia, America, Antarctica, and Australia. When sea levels were lower during
13625-464: The view that there are only three continents: Antarctica, Australia-New Guinea, and a single mega-continent which joins Afro-Eurasia and America via the contiguous continental shelf in and around the Bering Sea. The vast size of the latter compared to the first two might even lead some to say it is the only continent, the others being more comparable to Greenland or New Zealand. As a cultural construct ,
13750-411: The warming back to 1.5 °C (2.7 °F) above preindustrial levels or lower (such as through large-scale carbon dioxide removal ) would arrest the losses, but still cause greater ultimate sea level rise than if the threshold had never been exceeded. Further, 1.5 °C (2.7 °F) itself appears to commit the ice sheet to 1.4 m ( 4 + 1 ⁄ 2 ft) of sea level rise. The island
13875-590: The west coast was settled by Icelanders and Norwegians , through a contingent of 14 boats led by Erik the Red. They formed three settlements—the Eastern Settlement , the Western Settlement , and the Middle Settlement —on fjords near the southwestern tip of the island. They shared the island with the late Dorset culture inhabitants, who occupied the northern and western parts, and later with those of
14000-460: The winter. The United States tried to construct a subterranean network of secret nuclear missile launch sites in the Greenlandic ice cap, named Project Iceworm . According to documents declassified in 1996, this project was managed from Camp Century from 1960 to 1966 before abandonment as unworkable. The missiles were never fielded, and necessary consent from the Danish Government to do so
14125-482: The winters, in which "the old and helpless were killed and thrown over cliffs". These Norse settlements vanished during the 14th and early 15th centuries. The demise of the Western Settlement coincides with a decrease in summer and winter temperatures. A study of North Atlantic seasonal temperature variability during the Little Ice Age showed a significant decrease in maximum summer temperatures beginning about
14250-403: The world's sea level would rise by more than 7 m (23 ft). In 2003, a small island, 35 m × 15 m (115 ft × 49 ft) in length and width, was discovered by arctic explorer Dennis Schmitt and his team at the coordinates of 83-42 . Whether this island is permanent is not yet confirmed. If it is, it is the northernmost permanent known land on Earth. In 2007,
14375-506: The world: Africa - Eurasia - America , Antarctica , and Australia - New Guinea ( Sahul ). There are several ways of distinguishing the continents: In the English-speaking countries, geographers often use the term Oceania to denote a geographical region which includes most of the island countries and territories in the Pacific Ocean , as well as the continent of Australia . Zealandia (a submerged continent ) has been called
14500-451: Was declared the sole official language of Greenland at the historic ceremony. Tourism increased significantly between 2015 and 2019, with the number of visitors increasing from 77,000 per year to 105,000. One source estimated that in 2019 the revenue from this aspect of the economy was about 450 million kroner (US$ 67 million). Like many aspects of the economy, this slowed dramatically in 2020 and into 2021, due to restrictions required as
14625-410: Was extended to Greenlanders. Danish policies toward Greenland consisted of a strategy of cultural assimilation — or de-Greenlandification. During this period, the Danish government promoted the exclusive use of the Danish language in official matters, and required Greenlanders to go to Denmark for their post-secondary education. Many Greenlandic children grew up in boarding schools in southern Denmark, and
14750-575: Was inhabited by the Saqqaq culture . Most finds of remains from that period have been around Disko Bay , including the site of Saqqaq, for which the culture is named. From 2400 BC to 1300 BC, the Independence I culture existed in northern Greenland. It was a part of the Arctic small-tool tradition . Towns, including Deltaterrasserne , appeared. About 800 BC, the Saqqaq culture disappeared and
14875-435: Was known to extend, confirming that this was a land of continental proportions. On return to Europe, an account of the voyage, called Mundus Novus ("New World"), was published under Vespucci's name in 1502 or 1503, although it seems that it had additions or alterations by another writer. Regardless of who penned the words, Mundus Novus credited Vespucci with saying, "I have discovered a continent in those southern regions that
15000-429: Was never sought. The Danish government did not become aware of the programme's mission until 1997, when they discovered it while looking, in the declassified documents, for records related to the crash of a nuclear equipped B-52 bomber at Thule in 1968. With the 1953 Danish constitution, Greenland's colonial status ended as the island was incorporated into the Danish realm as an amt (county). Danish citizenship
15125-705: Was occupied by Nazi Germany . On 8 April 1941, the United States occupied Greenland to defend it against a possible invasion by Germany. The United States' occupation of Greenland continued until 1945. Greenland was able to buy goods from the United States and Canada by selling cryolite from the mine at Ivittuut . In World War II , the United States military used Bluie as a code name for Greenland, where they kept several bases named "Bluie (East or West) (sequential numeral)". The major air bases were Bluie West-1 at Narsarsuaq and Bluie West-8 at Søndre Strømfjord (Kangerlussuaq), both of which are still used as Greenland's major international airports. During this war,
15250-647: Was part of the very ancient Precambrian continent of Laurentia , the eastern core of which forms the Greenland Shield, while the less exposed coastal strips become a plateau. On these ice-free coastal strips are sediments formed in the Precambrian , overprinted by metamorphism and now formed by glaciers, which continue into the Cenozoic and Mesozoic in parts of the island. In the east and west of Greenland there are remnants of flood basalts and igneous intrusions, such as
15375-592: Was presented in 1950, which recommended the introduction of a modern welfare state with Denmark's development as sponsor and model. In 1953, Greenland was made an equal part of the Danish Kingdom. Home rule was granted in 1979. In 1867, United States Secretary of State William H. Seward worked with former senator Robert J. Walker to explore the possibility of buying Greenland and, perhaps, Iceland . Opposition in Congress ended this project. Following World War II,
15500-416: Was used in translating Greek and Latin writings about the three "parts" of the world, although in the original languages no word of exactly the same meaning as continent was used. While continent was used on the one hand for relatively small areas of continuous land, on the other hand geographers again raised Herodotus's query about why a single large landmass should be divided into separate continents. In
15625-660: Was viewed as running from the Black Sea through Kerch Strait , the Sea of Azov and along the Don River (known then as the Tanais ) in Russia . The boundary between Asia and Africa was generally taken to be the Nile River. Herodotus in the 5th century BCE objected to the whole of Egypt being split between Asia and Africa ("Libya") and took the boundary to lie along the western border of Egypt, regarding Egypt as part of Asia. He also questioned
