Continental drift, modern era. Map of the Earth showing the continents as they are today, 200 million years after the start of the break-up of the ancient supercontinent of Pangea. The Earth's continents move over the surface of the Earth, driven by movements of the fluid mantle below the crust. As the movement of the continents continues, a new supercontinent, called Pangea Ultima, will form in about 250 million years. For the complete set of illustrations of Pangea and Pangea Ultima, from 200 million years ago to 250 million years in the future, with and without labels, and with versions with extra land, see images C046/9220 to C046/9249. For this map with labels, see image C046/9241.
