Question

Quizplus · Accepted Answer

The majority of plate motion is driven by the spreading and upwelling of magma at mid-ocean ridges, where new oceanic lithosphere is created and pushes the existing plates away from each other. While subduction zones and collision zones can also contribute to plate motion, they typically do not produce as significant of a pushing force as mid-ocean ridges. The interiors of continental plates generally do not experience as much motion as the boundaries between plates.
