Which of the following is true about convection in Earth's mantle and tectonic plate motion?

Question

A.
Plate motion and mantle convection are related processes, but they cannot occur at the same time.
B.
Plate motion and mantle convection do not relate to each other in any way.
C.
Evidence suggests that plate motion and mantle convection are related processes.
D.
Evidence suggests that mantle convection stops plate motion from occurring.

Answer 1

C. Evidence suggests that plate motion and mantle convection are related processes.

Mantle convection is a key driving force of plate tectonics, as the movement of hotter, less dense material rising and cooler, denser material sinking in the mantle contributes to the movement of tectonic plates above.
