MASS MOVEMENT IN GEOLOGY Definition: Mass movement, also known as mass wasting, is the downslope movement of soil, rock, and debris under the influence of gravity. It does not require a transporting medium like water, wind, or ice. Features It occurs when the force of gravity overcomes the strength of materials on a slope. Mass movement can be rapid (like landslides or rockfalls) or slow (like soil creep). It is often triggered by factors such as rainfall, earthquakes, volcanic activity, or huma
