A possible "driving force" for plate motions is

Question

Quizplus · Accepted Answer

Convection in the asthenosphere is considered the most likely driving force for plate motions. As hot material rises from the mantle, it pushes on the overlying plates, causing them to move away from the rising material. As the material cools and sinks back down, it pulls the plates with it. This continuous cycle of rising and sinking material drives plate motion. The other options listed (A, B, and D) are all related to plate tectonics and can have effects on the movement of plates, but they are not considered the primary driving force for plate motion.
