Question

what causes the earths plates to move? convection currents in the mantle ocean currents weather currents contraction theory

Explanation:

The Earth's tectonic plates move due to convection currents in the mantle. The mantle is a layer of semi - molten rock below the crust. Heat from the Earth's core causes the mantle material to heat up, become less dense, and rise. As it rises, it cools, becomes more dense, and sinks. This circular motion (convection current) creates forces that move the overlying tectonic plates. Ocean currents are related to the movement of ocean water, weather currents are related to atmospheric movements, and the contraction theory is an outdated idea about the cooling and shrinking of the Earth (not related to plate movement).

Answer:

A. Convection Currents in the Mantle
