B) a rock avalanche
C) a rock fall
D) a rock slide

Question

Quizplus · Accepted Answer

A slump is a type of mass wasting where the material moves along a curved surface in a rotational motion. This occurs when a weakened or saturated layer of soil or rock slides downwards and rotates along the slip surface. A rock avalanche, rock fall, and rock slide all typically have a more linear motion rather than a rotational one.
