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.
Continental drift was not widely accepted when it was first proposed because ____. A. Wegener couldn't explain why or how the continents moved. B. continental landmasses were too big to move slowly over Earth's surface. C. magnetic and sonar data proved that Wegener's hypothesis was incorrect. D. mantle convection currents weren't in motion at that time.
