Africa-Eurasia is made up of the continents Africa and Eurasia ( Europe and Asia ). With an area of about 85 million square kilometers, Africa-Eurasia covers one sixth of the earth's surface and comprises well over half of all mainland on earth. With a population of 6.1 billion people (as of 2013), the major continent is home to around 87% of the world's population .
As in the case of Eurasia , many scholars in Africa-Eurasia also argue that the subdivision of the “world island” is not justified and is merely a historical and cultural one. Traditionally, the Isthmus of Suez is seen as the border between Africa and Eurasia .
From a geological point of view, Africa-Eurasia is relatively young and has existed in its present form for around 20 million years. After the disintegration of the supercontinent Pangea in the Mesozoic , Eurasia and North America belonged to the "northern continent" Laurasia , while Africa was part of the "southern continent" Gondwana (along with South America, Australia, Antarctica and India), two land masses completely separated from each other by the Tethys Ocean . After the disintegration of Gondwana , Africa and India began to move north in the Cretaceous Period, colliding with Eurasia in the Paleogene and Neogene .
The collision between Africa and Europe will cause the Mediterranean Sea to close in around 50 million years and a mountain range comparable to the Himalayas will rise in its place.
