Question

1. what do scientists think is the major driving force behind plate movements?

slab pull
ridge push
convection
divergent boundaries

Explanation:

Current scientific consensus identifies slab pull, the gravitational pull of dense, subducting tectonic slabs into the mantle, as the primary driving force for plate tectonic movement. Ridge push, convection, and divergent boundaries play secondary or related roles but are not considered the major driving force.

Answer:

slab pull
