According . to Alfred Wegener, the super-continent of Pangea began to break up 200 million years ago with the continents attaining the size, shape, and location where we see them today. This movement of continents has not yet come to an end. According to J. Tuzo Wilson, the breakup and drifting of the present continents . Seismology- lecture 5. Barbara Romanowicz, UC Berkeley.
