North America didn’t always have its familiar shape, nor its famed mountains, canyons, and plains: all of that was once contained in an unrecognizable mass, buried deep in Rodinia, a huge supercontinent that lay on the face of the Earth. Peter J. Haproff explains how it took millions of years and some incredible plate tectonics to forge the continent we know today.
