continental drift definition. A term, no longer used by geologists, that refers to the fact that continents are not stationary, but move across the Earth's surface. Continental drift is one feature of the modern theory of plate tectonics. (See Pangaea.)
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.
