Template:Infobox Continent


Afro-Eurasia,[1] also Afrasia,[2] Eurafrasia[2] or Eufrasia,[3] is the largest landmass on Earth. It may be defined as a supercontinent, with the term being a portmanteau of its constituent parts Africa and Eurasia (further divided into Europe and Asia) which are joined together at the Isthmus of Suez.[4] Afro-Eurasia encompasses 84,980,532 square kilometers and has a population of approximately 6 billion people, or roughly 85% of the world population.[5] It is also known as the Old World, as opposed to the Americas, Antarctica and Oceania, which are known as the New World.

The mainland of Afro-Eurasia has been referred to as the World Island, a term coined by Sir Halford John Mackinder in The Geographical Pivot of History.[6] (The term excludes non-mainland islands and archipelagos.) It was the original scope of the word 'continent'.[7]

Geology

Africa is joined to Asia by a land bridge. Africa is expected to collide with Europe more than 600,000 years from now, when the Strait of Gibraltar closes. When this happens, the Mediterranean Sea will be isolated from the Atlantic Ocean. More than 50 million years from now the Mediterranean is expected to disappear as the collision pushes up new mountain ranges.[8]

Divisions

Normally Afro-Eurasia is divided at the Suez Canal into Africa and Eurasia, the latter of which can be subdivided into Europe and Asia. It has also been divided into Eurasia-North Africa and Sub-Saharan Africa for cultural and historical reasons.[9]
