1 UNIFYING THEORY OF PLATE TECTONICS By: Gilberto E. Trevino & Dorien Gray

2  Plate tectonics describe how the earth's plates move around. This movement affects subduction, sea floor spreading, volcanic activity, mountain building, and other geological features.

3 ALL OF THE CONTINENTS WERE ONE…

4  The continents move at the same rate as our finger nails grow.  That rate is 3 millimeters a month.

5 PLATE TECTONICS MOVE BECAUSE THEY ARE FLOATING ON TOP OF LIQUID MANTLE AND THE MANTLE MOVES BECAUSE OF CONVECTION CURRENTS.

6 ALFRED WEGENER PUBLISHED THE THEORY OF CONTINENTAL DRIFT.

7 PANGAEA  200-250 million years ago a super continent called Pangaea existed. Over time the plate tectonics caused it to separate, forming our continents today.

8  Pangaea is “all of earth” in Latin and was named by Alfred Wegener in 1915.  Researchers believe that one day the continents America and Asia will come back together and form a supercontinent called Amasia.
