North America, Permian period. Image 3 of 9. Computer artwork of the Permian period stage (approximately 299 to 251 million years ago) of a sequence showing the formation of the North American continent. The continents are slowly moved over the surface of the Earth by currents in the fluid mantle below the crust. Over millions of years the continents moved into the positions they are in today. For North America at different points throughout prehistory, see images E402/153 to E402/161.
