Why is the mantle important to the movement of Earth's plates?

Question

A.

Conduction from the core creates strong magnetic fields in the mantle, which help to move Earth's plates.
B.

Pressure from the core creates convection currents in the mantle, which help to move Earth's plates.
C.

Heavy metals in the mantle create strong magnetic fields, which help to move Earth's plates.
D.

Temperature differences in the mantle create convection currents, which help to move Earth's plates.

Answer 1

D.
Temperature differences in the mantle create convection currents, which help to move Earth's plates.

The movement of Earth's plates is driven by the convection currents in the mantle, which are caused by temperature differences. As the mantle material heats up and cools down, it becomes less dense and rises or sinks, creating a circulating flow of material. This convection movement is responsible for the shifting and movement of Earth's tectonic plates.
