NettetOne of the common mass movements are landslides. 1. Landslide A landslide is the movement of rock, debris or earth down a slope. They result from the failure of the materials which make up the hill slope and are driven by the force of gravity. Landslides are known also as landslips, slumps or slope failure. NettetHowever, if the slope angle becomes steeper or if the earth material is weakened, shear force exceeds normal force, compromising shear strength, and downslope movement occurs. Figure \(\PageIndex{1}\): As slope increases, the force of gravity (fg) stays the same and the normal force decreases while the shear force proportionately increases.

The term landslide is often used as a synonym for mass wasting , but mass wasting is a much broader term referring to all movement downslope. Geologically, landslide is a general term for mass wasting that involves fast-moving geologic material.
