Which statement about continental drift is true?

Question

Quizplus · Accepted Answer

Continental drift is caused by the movement of tectonic plates, which float on top of the Earth's mantle. This movement is driven by convection currents in the mantle, not by the sun. Rising magma can cause pressure on the plates and lead to the movement of continents. The idea of continental drift was not immediately accepted and was heavily debated and criticized for many years before it gained widespread acceptance in the scientific community. Deep rift valleys, such as those found in East Africa, are actually evidence of plate tectonics and the process of continental drift.
