It was a century ago this spring that a little-known German meteorologist named Alfred Wegener proposed that the continents had once been massed together in a single supercontinent and then gradually drifted apart. He was, of course, right.
The continental drift theory is the theory that once all the continents were joined in a super-continent, which scientists call Pangaea. Over a vast period of time, the continents drifted apart to their current locations.Alfred Wegener first supported continental drift. Wegenerâs explanation of continental drift in 1912 was that drifting occurred because of the earthâs rotation. This explanation and his theory were not widely accepted.Prior to Wegener, however, many had noted that the shapes of the continents seem to fit together, suggesting some schism in the past. Before the 1950s, the concept of the continental drift, for the most part, was not even entertained as plausible.he continental drift theory is the theory that once all the continents were joined in a super-continent, which scientists call Pangaea.
