The most rapid type of mass movement, in which rocks ranging from large masses to small fragments are loosened from the face of a cliff.
an extremely rapid, and potentially dangerous, downslope movement of earth materials
Falling, bouncing, and rolling of debris down slope.
Moving mass of rock fragments that has broken loose from an outcrop and cascaded down a slope.
Rapid fall of a detached piece of bedrock from a cliff or steep slope.
