Continental drift,200 million years ago,showing the Earth at the time of the break-up of the ancient supercontinent of Pangea. This supercontinent formed around 300 million years ago. The Earth's continents move over the surface of the Earth,driven by movements of the fluid mantle below the crust. Several such supercontinents have formed in the 4.5-billion-year history of the Earth,and it is thought that a future supercontinent,called Pangea Ultima,will form in around 250 million years time | |
