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.
This slideshow explains Wegener's theory. Earth around 200 million years ago, at the time of Pangaea. Wegenerâs evidence for continental drift was that: 1  the same types of fossilised animals and plants are found in South America and Africa.efore Wegener developed his theory, it was thought that mountains formed because the Earth was cooling down, and in doing so contracted.
