What is the driving force for plate tectonics? A. Gravity slab pull
B. The gravity of the Moon and Sun
C. Heat from the Earth's core causing mantle convection

Option C

Explanation:

Driving force for plate tectonics is the "convection in the Earths mantle" or option C. Convection is the transfer of heat due to the movement in molecules also causing hot to rise and cold to sink. Convection currents cause the tectonic plates to move because the currents rise to the Earths surface forcing the plates to drive away from each other also known as seafloor spreading.

Hope this helps
