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

Answer 1

The correct answer is:

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

Mantle convection currents drive the movement of tectonic plates, causing them to move in various directions based on the flow of the molten rock underneath.
