Which of the following is true about tectonic plate motion?

Question

A.
Tectonic plates move in directions that are opposite the directions of underlying mantle convection currents.
B.
Tectonic plate motion is not related in any way to mantle convection currents.
C.
All tectonic plates move in the same direction and at the same rate.
D.
Tectonic plates move in directions that closely match the directions of underlying mantle convection currents.

Answer 1

The correct answer is:

D. Tectonic plates move in directions that closely match the directions of underlying mantle convection currents.

Tectonic plate motion is primarily driven by mantle convection, where the heat from the Earth's interior causes the mantle to circulate and drive the movement of the plates above it.
