The correct response that specifically explains how crustal deformation builds landforms is:
When two tectonic plates start to push into each other they can rise up and build mountains, or sink under and create deep valleys.
This statement accurately describes the processes of crustal deformation, which involve the interaction of tectonic plates. When plates collide (converge), they can lead to the formation of mountain ranges through uplift or cause one plate to subduct beneath another, creating deep oceanic trenches or valleys.
