Afro-Eurasia encompasses 84,980,532 km2 (32,811,167 sq mi), 57% of the world's land area, and has a population of approximately 6.7 billion people, roughly 86% of the world population. Together with Australia, it comprises the vast majority of land in the world's Eastern Hemisphere. The Afro-Eurasian mainland is the largest and most populous contiguous landmass on Earth.

Geology

Although Afro-Eurasia is typically considered to comprise two or three separate continents, it is not a proper supercontinent. Instead, it is the largest present part of the supercontinent cycle.[3]

Past

The oldest part of Afro-Eurasia is probably the Kaapvaal Craton, which together with Madagascar and parts of India and western Australia formed part of the first supercontinent Vaalbara or Ur around 3 billion years ago. It has made up parts of every supercontinent since. At the breakup of Pangaea around 200 million years ago, the North American and Eurasian Plates together formed Laurasia while the African Plate remained in Gondwana, from which the Indian Plate split off. Upon impact with the Eurasian Plate, the Indian Plate created southern Asia around 50 million years ago and began the formation of the Himalayas. Around the same time, the Indian Plate also fused with the Australian Plate.

Conventionally, Africa is joined to Eurasia only by a relatively narrow land bridge (which has been split by the Suez Canal at the Isthmus of Suez) and remains separated from Europe by the straits of Gibraltar and Sicily.

Future

Amasia, and Pangaea Proxima.[7] In the first two, the Pacific closes and Africa remains fused to Eurasia, but Eurasia itself splits as Africa and Europe spin towards the west; in the last, the trio spin eastward together as the Atlantic closes, creating land borders with the Americas

When that was shut off sometime between 6.5 to 6 MYBP, net evaporative loss set in at the rate of around 3,300 cubic kilometers yearly. At that rate, the 3.7 million cubic kilometres of water in the basin would dry up in scarcely more than a thousand years, leaving an extensive layer of salt some tens of meters thick and raising global sea level about 12 meters.
