Continental Drift Theory

Continental Drift is the theory proposed by meteorologist Alfred Wegener in 1915, hypothesizing that there was once a supercontinent that joined all land masses over the earths mantle, called Pangaea, that slowly started to break up 190 million years ago. These broken up continents went on to become all the land masses that are on earth today.
Evidence supporting this theory are continental shapes, fossil distribution, palaeoclimates, age of rocks and sediments, direct measurements, cross-continental and geological formaions and glacial deposits.

This stop motion clip demonstrates the breakup of Pangaea over many years until present day by continental drift.

  1. Good intro Bongavo. We will also look at other evidence as a group for drift - paleomagnetism and polar wandering.
