Question

the theory of plate tectonics is the unifying theory of geology. explain the role of mantle convection and slab pull in driving the movement of tectonic plates. 4 points your answer

Explanation:

Mantle convection involves heated lower mantle material rising, cooling at the surface, and sinking—creating currents that push tectonic plates. Slab pull occurs when dense oceanic crust subducts into the mantle, pulling the rest of the plate along, which is a major driver of plate movement. Both processes work together to drive plate tectonics.

Answer:

Mantle convection creates circular currents in the mantle that push tectonic plates. Slab pull happens when dense subducting oceanic plates pull the rest of the plate downward. Together, these processes drive plate movement.
