 As this scenario continues , by 100 million years from the present the continental spreading will have reached its maximum extent and the continents will then begin to coalesce . In 250 million years , North America will collide with Africa while South America will wrap around the southern tip of Africa . The result will be the formation of a new supercontinent ( sometimes called Pangaea Ultima ) , with the Pacific Ocean stretching across half the planet . The continent of Antarctica will reverse direction and return to the South Pole , building up a new ice cap .

 Christopher Scotese and his colleagues have mapped out the predicted motions several hundred million years into the future as part of the Paleomap Project . In their scenario , 50 million years from now the Mediterranean sea may vanish and the collision between Europe and Africa will create a long mountain range extending to the current location of the Persian Gulf . Australia will merge with Indonesia , and Baja California will slide northward along the coast . New subduction zones may appear off the eastern coast of North and South America , and mountain chains will form along those coastlines . To the south , the migration of Antarctica to the north will cause all of its ice sheets to melt . This , along with the melting of the Greenland ice sheets , will raise the average ocean level by 90 m ( 300 ft ) . The inland flooding of the continents will result in climate changes .
