Quizplus · Accepted Answer

A slump is characterized by a crescent-shaped scarp face, which is formed when a mass of rock or unconsolidated material moves along a curved surface. Debris flows are typically more fluid-like and lack a distinct scarp face. Solifluction refers to slow downslope movement of soil due to freezing and thawing, and rock glaciers are a type of permafrost feature in which blocks of rock are frozen within a mass of ice.
