Which type of mass wasting involves the rapid downslope movement of a coherent block of earth or rock along a curved planar surface?

💡 Solution & Explanation

Slump is a geologic process characterized by the rapid downslope displacement of coherent blocks of earth or rock along a distinct concave slip surface. Unlike rockfalls which involve free-falling debris or creep which is extremely slow, slumping preserves the general internal structure of the moving mass. Mass wasting classifications are a staple area for physical geography and disaster management preparation.
