Mass Wasting and landform development ± Mass wasting refers to the downslope movement of rock, regolith, and soil under the direct influence of gravity ± Role of mass wasting ± Geologic process that often follows weathering ± Combined effects of mass wasting and running water produce stream valleys

Mass Wasting and landform development ± For mass wasting to occur, there must be a slope angle ± Most rapid events occur in areas of rugged, geologically young mountains ± As a landscape ages, less dramatic downslope movements occur

Controls and triggers of mass wasting ± Gravity is the controlling force ± Important triggers include ± Saturation of the material with water Diminishes particle cohesion Water adds weight ± Oversteepening of slopes Stable slope angle ( angle of repose ) is different for various materials
