Question

5 which process occurs in the mantle and is thought to be the force behind plate tectonics?
a plate boundary
b divergent boundary
c normal fault
d convection current

Explanation:

Plate boundaries (A) are locations where tectonic plates meet, not a driving process. Divergent boundaries (B) are a type of plate boundary, not the force behind movement. Normal faults (C) are fractures in crust from stress, unrelated to mantle-driven plate motion. Convection currents in the mantle, caused by heat from the core, create the movement that drives plate tectonics.

Answer:

D. convection current
