The theory of continental drift was not accepted for many years. One problem was that a plausible driving force was missing. A second problem was that Wegener's estimate of the velocity of continental motion, 250 cm/year, was implausibly high.(The currently accepted rate for the separation of the Americas from Europe and Africa is about 2.5 cm/year). And it did not help that Wegener was not a geologist.s late as 1953 â just five years before Carey introduced the theory of plate tectonics â the theory of continental drift was rejected by the physicist Scheidegger on the following grounds.
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.d. Continental drift theory also gained in popularity because of the theory of plate tectonics. Briefly, plate tectonics suggests that the ocean floor began to spread and that the continents existed on âplatesâ that moved in response to the changing ocean floor.
