What drives the motion of the continental plates on Earth?

Question

Quizplus · Accepted Answer

The motion of the continental plates on Earth is primarily driven by the convection cells in the mantle, which cause the plates to move and eventually collide or drift apart. This is known as plate tectonics. Other factors, such as the rotation of the liquid core and Earth's magnetic field, may play a role in plate motion but are not the primary drivers. Lava flows in trenches and tidal forces are also not the main factors influencing plate motion.
