A force that is important in driving plate tectonics is:

A) slab pull
B) ridge push
C) upwelling mantle, such as in hot spots
D) all of these

Slab Pull

A plate-driving force generated by the sinking action of a relatively dense, subducted slab.

Ridge Push

A plate-driving force that results from the tendency of an oceanic plate to slide down the sloping lithosphere-asthenosphere boundary near a mid-ocean ridge.

Upwelling Mantle

Refers to the process where hotter, less dense mantle material ascends towards the Earth's surface, typically at mid-ocean ridges or hotspots.
