13. what are two of the processes that move tectonic plates over the surface of the earth?

Answer choices are:

A. Slab pull and crust conversion

B. Plate movement and convection currents

C. Connection and convection

D. Ridge push and slab pull

Correct answer choice is:

D. Ridge push and slab pull

Explanation:

Ridge Push: The process that occurs when magma arises at a mid-ocean ridge and drives oceanic plates in two separate ways apart from the ridge.

Slab pull: The process that occurs if a thick oceanic plate settles underneath a more resilient plate with a subduction zone, drawing the excess of the plate that pursues following it.
