                       Continental Drift


         •     The earth was initially a super
               continent called Pangea 250
               million years ago.

         •     Plates move a few centimetres a
               year, but this adds up to
               thousands of kilometres over
               millions of year.

         •     This movement is called Tectonic
               drift.
