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 . Radoslav . Fujerik. Continental Technology Center .

The movement can cause mountains and valleys to form.. Earthquakes usually happen at plate boundaries, called faults, when the plates get caught and then jerk loose. . 2019. GEO 5/6690 Geodynamics.
