GENERAL GEOLOGY

Detailed explanation-1: -Landslides are a type of “mass wasting, ” which denotes any down-slope movement of soil and rock under the direct influence of gravity. The term “landslide” encompasses five modes of slope movement: falls, topples, slides, spreads, and flows.

Detailed explanation-2: -Rockfall is the free or bounding fall of rock debris down steep slopes under the influence of gravity.

Detailed explanation-3: -What is a landslide? A landslide is a mass movement of material, such as rock, earth or debris, down a slope. They can happen suddenly or more slowly over long periods of time.

Detailed explanation-4: -Gravity causes the downhill movement of rock and soil material, which is known as mass wasting. The term “landslide” is frequently used interchangeably with “mass wasting.” The movement caused by mass wasting can be slow or fast. Rapid movement, such as during debris flows, can be hazardous.

Detailed explanation-5: -Mass wasting is the downhill movement of rock and soil material due to gravity. 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.
