Bilang pambuo ng kultura, lumalagpas sa kalapagang kontinental ang saklaw ng isang kontinente at sinasama ang mga mga nabasag na bahagi nito mikrokontinente at isla sa karagatan.
Kung susundin naman ito, mapapabilang din ang islang bansa ng Islandiya sa Europa at ang Madagascar naman sa Aprika.
Kung ipipilit ang pinakatugatog ng konseptong ito, mapapabilang ang mga isla at kapuluang bansa sa platong kontinental ng Awstralya sa isang malakontinenteng quasi-continent tinatawag na Osiyanya Oceania.
Sa gayon, nahahati ang kalupaan ng Daigdig sa mga kontinente o malakontinente. Di ganong kahigpit ang pamantayan para sa kung ano ang "magkakahiwalay at magkakaibang kalupaan" na maituturing na kontinente sa hindi, dahil na rin sa kasaysayan.
Sa pitong kinikilalang kontinente ng karamihan, tanging ang mga kontinente lang ng Antartika at Awstralya ang mga napapaligiran ng katubigan at nakahiwalay nang buo sa iba pang mga kontinente.
Karamihan sa mga ito ay di eksaktong magkakahiwalay at magkakaiba kundi pwede na " more or less distinct continents". Sa dalawang nabanggit na halimbawa, hindi sila eksaktong pinaghihiwalay ng kung anuman parehong gawang-tao, mababaw, at makitid ang mga Agusan ng Suez at Panama , kaya hindi ito itinuturing na nagpapahiwalay.
Masyadong maliit ang mga dalahikang ito kumpara sa mga gahiganteng lupain na pinagdudugtong nila. Sa modelo ng pitong kontinente, itinuturing ang dalawang Amerika bilang mga magkakahiwalay na kontinente.
Gayunpaman, maaari ring ituring silang iisa - ang kontinente ng Amerika o ang Kaamerikahan. Ang ganitong pananaw ay laganap sa Estados Unidos hanggang noong Ikalawang Digmaang Pandaigdig , at nananatili pa ring sikat ito sa ilang bahagi sa Asya na sumusunod sa anim na kontinenteng modelo.
Samantala, tinatanggal kadalasan sa usapan ang pamantayan ng pagkakahiwa-hiwalay kung hahatiin ang magkarugtong na kontinente ng Eurasya sa dalawa - ang mga kontinente ng Asya at Europa.
Kung pag-uusapan ang pisikal na heograpiya, itinuturing na tangway lamang ang Europa at Timog Asya ng kalupaang Eurasya.
Gayunpaman, madalas itinuturing na kontinente ang Europa dahil sa kabuuang lawak ng lupang maikukumpara sa ibang kontinente: 10,, kilometro kuwadrado 3,, milya kuwadrado.
Kalahati lang sa sukat na iyon ang kabuuang lawak ng Timog Asya, kaya madalas itong itinuturing na subkontinente. Sa modelo ng anim na kontinente, may iisang kontinente ng Eurasya lamang.
Isa itong alternatibong pagtingin na ginagamit sa larangan ng heolohiya at heograpiya. May ilang naniniwala na ang pananaw ng magkahiwalay na Europa at Asya ay isang iniwan na bakas ng Eurosentrismo : " kung titingnan ang pagkakaiba-iba sa pisikal, kultura, at kasaysayan, maikukumpara ang Tsina at India sa kabuuan ng kalupaan ng Europa, di sa iisang bansang Europeo.
Kung mahigpit ang pamantayan na ang kontinente ay isa dapat na "magkakahiwalay at magkakaiba," mabubuo ang iisang kontinente ng Apro-Eurasya mula sa pinagsamang mga kontinente ng Aprika, Asya, at Europa.
Noong mas mababa pa ang taas ng katubigan noong kasagsagan ng Panahon ng Yelo ng Pleistoseno , mas marami ang nakalabas na bahagi ng kalupaan at gumagawa ng mga tulay na lupa.
Noong panahong iyon, magkakakonekta at hiwalay rin sa iba ang kontinente ng Awstralya binubuo ng Awstralya at Bagong Ginea.
Magkakonekta rin ang mga kontinente ng Apro-Eurasya at Kaamerikahan sa tulong ng tulay na lupa ng Bering. Continental crust is only known to exist on Earth.
Oceanic islands are frequently grouped with a neighbouring continent to divide all the world's land into 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 a region called Oceania.
By convention, "continents are understood to be large, continuous, discrete masses of land, ideally separated by expanses of water.
Earth 's major landmasses all have coasts on a single, continuous World Ocean , which is divided into a number of principal oceanic components by the continents and various geographic criteria.
The most restricted meaning of continent is that of a continuous  area of land or mainland, with the coastline and any land boundaries forming the edge of the continent.
In this sense, the term continental Europe sometimes referred to in Britain as "the Continent" is used to refer to mainland Europe, excluding islands such as Great Britain , Iceland , Ireland , and Malta while the term continent of Australia may refer to the mainland of Australia , excluding New Guinea , Tasmania , and other nearby islands.
Similarly, the continental United States refers to the 48 contiguous states and the District of Columbia and may include Alaska in the northwest of the continent the two being separated by Canada , while excluding Hawaii in the Pacific Ocean.
From the perspective of geology or physical geography , continent may be extended beyond the confines of continuous dry land to include the shallow, submerged adjacent area the continental shelf  and the islands on 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.
As a cultural construct , the concept of a continent may go beyond the continental shelf to include oceanic islands and continental fragments.
In this way, Iceland is considered part of Europe and Madagascar part of Africa. Extrapolating the concept to its extreme, some geographers group the Australian continental plate with other islands in the Pacific into one "quasi-continent" called Oceania.
This divides the entire land surface of Earth into continents or quasi-continents. The ideal criterion that each continent is a discrete landmass is commonly relaxed due to historical conventions.
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". In both cases, there is no complete separation of these landmasses by water disregarding the Suez Canal and Panama Canal , which are both narrow and shallow, as well as man-made.
Both these isthmuses are very narrow compared to the bulk of the landmasses they unite. North America and South America are treated as separate continents in the seven-continent model.
However, they may also be viewed as a single continent known as America. The criterion of a discrete landmass is completely disregarded if the continuous landmass of Eurasia is classified as two separate continents: Europe and Asia.
Physiographically, Europe and South Asia are peninsulas of the Eurasian landmass. The alternative view—in geology and geography—that Eurasia is a single continent results in a six-continent view of the world.
Some view 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.
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.
When sea levels were lower during the Pleistocene ice ages , greater areas of continental shelf were exposed as dry land, forming land bridges between Tasmania and Australian mainland.
At those times Australia—New Guinea was a single, continuous continent. Other islands such as Great Britain were joined to the mainlands of their continents.
There are several ways of distinguishing the continents:. As previously mentioned, some geographers use the name Oceania for a region including most of the island countries and territories in the Pacific Ocean as well as the continent of Australia.
The following table summarizes the area and population of the continental regions used by the United Nations. Apart from the current continents, the scope and meaning of the term continent includes past geological ones.
Supercontinents , largely in evidence earlier in the geological record, are landmasses that comprise more than one craton or continental core. Over time, these supercontinents broke apart into large land masses which formed 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 notable examples are the Indian subcontinent and the Arabian Peninsula. In many of these cases, the "subcontinents" concerned are on different tectonic plates from the rest of the continent, providing a geological justification for the terminology.
Where the Americas are viewed as a single continent America , it is divided into two subcontinents North America and South America    or three with Central America being the third.
Some areas of continental crust are largely covered by the sea and may be considered submerged continents. Notable examples are Zealandia , emerging from the sea 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, is usually considered an island of Africa, but its divergent evolution has caused it to be referred to as "the eighth continent" from a biological perspective.
The Biodiversity Information Standards organization has developed the World Geographical Scheme for Recording Plant Distributions , used in many international plant databases.
This scheme divides the world into nine "botanical continents", some match the traditional geographical continents, but some differ significantly.
Asia Minor ,  The first distinction between continents was made by ancient Greek mariners who gave the names Europe and Asia to the lands on either side of the waterways of the Aegean Sea , the Dardanelles strait, the Sea of Marmara , the Bosporus strait and the Black Sea.
Ancient Greek thinkers subsequently debated whether Africa then called Libya should be considered part of Asia or a third part of the world. Division into three parts eventually came to predominate.
Herodotus  in the 5th century BC 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 the division into three of what is really a single landmass,  a debate that continues nearly two and a half millennia later.
Eratosthenes , in the 3rd century BC, 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 the Black Sea and the Caspian Sea , and the border between Asia and Africa at the isthmus between the Red Sea and the mouth of Lake Bardawil on the Mediterranean Sea.
Through the Roman period and the Middle Ages , a few writers took the Isthmus of Suez as the boundary between Asia and Africa, but most writers continued to consider it the Nile or the western border of Egypt Gibbon [ citation needed ].
In the Middle Ages, the world was usually portrayed on T and O maps , with the T representing the waters dividing 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 West Indies in , sparking a period of European exploration of the Americas.
But despite four voyages to the Americas, Columbus never believed he had reached a new continent—he always thought it was part of Asia.
After reaching the coast of Brazil , they sailed a long way farther south along the coast of South America , confirming that this was a land of continental proportions and that it also extended much farther south than Asia was known to.
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 — Maps of this time though, still showed North America connected to Asia and showed South America as a separate land.
In 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 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.
From the 16th century the English noun continent was derived from the term continent land , meaning continuous or connected land  and translated from the Latin terra continens.
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.
Thus Europe, Asia, and Africa is one great continent, as America is another. From the late 18th century, some geographers started to regard North America and South America as two parts of the world, making five parts in total.
Overall though, the fourfold division prevailed well into the 19th century. Europeans discovered Australia in , but for some time it was taken as part of Asia.
By the late 18th century, some geographers considered it a continent in its own right, making it the sixth or fifth for those still taking America as a single continent.
Antarctica was sighted in during the First Russian Antarctic Expedition and described as a continent by Charles Wilkes on the United States Exploring Expedition in , the last continent identified, although a great "Antarctic" antipodean landmass had been anticipated for millennia.
From the midth century, atlases published in the United States more commonly treated North and South America as separate continents, while atlases published in Europe usually considered them one continent.
However, it was still not uncommon for American atlases to treat them as one continent up until World War II.
Some geographers regard Europe and Asia together as a single continent, dubbed Eurasia. Geologists use the term continent in a different manner from geographers.
In geology, a continent is defined by continental crust, which is a platform of metamorphic and igneous rock , largely of granitic composition.
Continental crust is less dense and much thicker than oceanic crust, which causes it to "float" higher than oceanic crust on the dense underlying mantle.
This explains why the continents form high platforms surrounded by deep ocean basins. Some geologists restrict the term 'continent' to portions of the crust built around stable regions called cratons.
Cratons have largely been unaffected by mountain-building events orogenies since the Precambrian.
A craton typically consists of a continental shield surrounded by a continental platform. The shield is a region where ancient crystalline basement rock typically 1.
The platform surrounding the shield is also composed of ancient basement rock, but with a cover of younger sedimentary rock.
This accounts for the great age of the rocks comprising the continental cratons. The margins of geologic continents are characterized by currently active or relatively recently active mobile belts and deep troughs of accumulated marine or deltaic sediments.
Beyond the margin, there is either a continental shelf and drop off to the basaltic ocean basin or the margin of another continent, depending on the current plate-tectonic setting of the continent.
A continental boundary does not have to be a body of water. By this definition, Eastern Europe, India and some other regions could be regarded as continental masses distinct from the rest of Eurasia because they have separate ancient shield areas i.
East European craton and Indian craton. Younger mobile belts such as the Ural Mountains and Himalayas mark the boundaries between these regions and the rest of Eurasia.
Plate tectonics provides yet another way of defining continents. Today, Europe and most of Asia constitute the unified Eurasian Plate , which is approximately coincident with the geographic Eurasian continent excluding India, Arabia, and far eastern Russia.
India contains a central shield, and the geologically recent Himalaya mobile belt forms its northern margin. North America and South America are separate continents, the connecting isthmus being largely the result of volcanism from relatively recent subduction tectonics.
Superkontinent mit Subkontinenten handelt. Geologisch umfasst ein Kontinent auch das ihm zugehörige Schelfgebiet , also den Festlandssockel im Flachmeer.
Neben diesen beiden gibt es auch eine historisch-politische Dimension. Beleg hierfür ist die Tatsache, dass Europa als eigener Erdteil gilt, obwohl dies keiner der genannten geografischen oder technischen Definitionen entspricht.
So stabil uns die heutige Verteilung der Landmassen auf der Erde auch erscheinen mag, so stellt sie erdgeschichtlich nur eine Momentaufnahme dar.
Anhand der o. Einige wenige Quellen   sind der Meinung wie bereits in der Unterrichtshilfe der Royal Geographic beschrieben , dass Ozeanien anstelle von Australien der korrekte Name dieses pazifischen Erdteils ist.
Zudem wurde der Begriff Doppelkontinent seit dem ausgehenden Jahrhundert für verschiedene geologische Landmassen genutzt — darunter Eurasien Europa und Asien  und Amerika Nord- und Südamerika  — und wird auch heute teilweise noch in primär geographischen und historischen Publikationen verwendet.
Der Versuch, die Anzahl der Kontinente auf dem Globus zu bestimmen, zieht sich durch die gesamte Zeitrechnung. Die Zähl- und Sichtweisen variieren stark.
Seine Dreiteilung wurde für das gesamte Altertum als verbindlich angesehen. Es existieren auch noch weitere davon abweichende Einteilungen. Zwei nennenswerte geologisch tektonische Modelle leiten sich aus dem erstmals publizierten Konzept von Alfred Wegener ab, dass zu Ende des Paläozoikums alle Kontinente in einem Superkontinent Pangaea vereinigt waren und sich langsam durch Aufspaltung aufgrund aktiven Vulkanismus voneinander im sog.
