Kontinente werden per Definition als durch Ozeane getrennte Festlandmasse bezeichnet. Parallel dazu wird die bevölkerte Welt in meist fünf Erdteile eingeteilt:. Ein Kontinent (lateinisch terra continens „zusammenhängendes Land“) ist eine geschlossene Festlandmasse. In vielen Sprachen stammt das Wort für Kontinent. Diese Kategorien enthalten neben geographischen Artikeln auch solche aus anderen Wikipedia-Fachgebieten wie zum Beispiel Wirtschaft, Verkehr, Kultur etc.

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.
North American continental rocks extend to Greenland a portion of the Canadian Shield , and in terms of plate boundaries, the North American plate includes the easternmost portion of the Asian landmass.
Geologists do not use these facts to suggest that eastern Asia is part of the North American continent, even though the plate boundary extends there; the word continent is usually used in its geographic sense and additional definitions "continental rocks," "plate boundaries" are used as appropriate.
Over geologic time, continents are periodically submerged under large epicontinental seas, and continental collisions result in a continent becoming attached to another continent.
The current geologic era is relatively anomalous in that so much of the continental areas are "high and dry"; that is, many parts of the continents that were once below sea level are now elevated well above it due to changes in sea levels and the subsequent uplifting of those continental areas from tectonic activity.
There are many microcontinents, or continental fragments , that are built of continental crust but do not contain a craton. Some of these are fragments of Gondwana or other ancient cratonic continents: Zealandia ,  which includes New Zealand and New Caledonia ; Madagascar ; the northern Mascarene Plateau , which includes the Seychelles.
Other islands, such as several in the Caribbean Sea , are composed largely of granitic rock as well, but all continents contain both granitic and basaltic crust, and there is no clear boundary as to which islands would be considered microcontinents under such a definition.
The Kerguelen Plateau , for example, is largely volcanic, but is associated with the break-up of Gondwanaland and is considered a microcontinent,   whereas volcanic Iceland and Hawaii are not.
The British Isles , Sri Lanka , Borneo , and Newfoundland are margins of the Laurasian continent—only separated by inland seas flooding its margins.
The movement of plates has caused the formation and break-up of continents over time, including occasional formation of a supercontinent that contains most or all of the continents.
The supercontinent Columbia or Nuna formed during a period of 2. The eight continents later re-assembled into another supercontinent called Pangaea ; Pangaea broke up into Laurasia which became North America and Eurasia and Gondwana which became the remaining continents.

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.

Ozeanische Inseln sind keine eigentliche Festlandmasse, sondern immer vulkanischer Natur, also Vulkane bzw. Die sieben Kontinente nehmen jeweils weniger als ein Zehntel der Erdoberfläche ein.
Die Besiedelung ist vom Klima und den vorhandenen Lebensgrundlagen abhängig. Auch aus geschichtlichen Gründen ist die Weltbevölkerung sehr ungleich verteilt.
Die Antarktis wird nur zeitweise von wenigen Forschern und Besuchern bewohnt. Weniger als ein Prozent der Weltbevölkerung lebt in Australien und Ozeanien.
Fast zwei Drittel leben jedoch in Asien, und diese vor allem in China und Indien. Die Namen der Kontinente sind in der ursprünglichen lateinischen Form alle weiblich und enden einheitlich auf -a.

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. Konektado rin ang iba pang mga isla noong panahon na iyon tulad ng Pilipinas at Gran Britanya sa pangunahing kalupaan ng mga kontinente.
Noon din panahong iyon, may tatlo lamang na kontinenteng magkakahiwalay at magkakaiba: ang kontinente ng Apro-Eurasya-Amerika, Antartika, at Awstralya-Bagong Ginea.
