Continental drift, 100 million years ago. Map of the Earth showing the continents some 100 million years after the start of the break-up of the ancient supercontinent of Pangea, and 100 million years before the modern era. The Earth's continents move over the surface of the Earth, driven by movements of the fluid mantle below the crust. This stage in the history shows the emerging shapes of some of today's continents. It will take another 350 million years from this point before the next supercontinent, Pangea Ultima, forms. 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 C046/9237.
