CONTINENTAL DRIFT. Observe the shape of the coastline of the Atlantic Ocean. You will be surprised by the symmetry of the coastlines on either side of the ocean. No wonder, many scientists thought of this similarity and considered the possibility of the two Americas, Europe and Africa, to be once joined together.
Alfred Wegener (1912) proposed:- A large super-continent PANGEA split into smaller fragments about 200-300 million years ago. These then drifted apart to form the present arrangement of continents.
