Mass wasting From Wikipedia, the free encyclopedia Mass wasting at Palo Duro Canyon , West Texas (2002) Talus cones produced by mass wasting, north shore of Isfjord , Svalbard , Norway . A rockfall in Grand Canyon National Park Mass wasting , also known as slope movement or mass movement , is the geomorphic process by which soil , regolith , and rock move downslope under the force of gravity . Types of mass wasting include creep, slides, flows, topples, and falls, each with its own characteristic features, and taking place over timescales from

seconds to years. Mass wasting occurs on both terrestrial and submarine slopes, and has been observed on Earth , Mars , Venus , and Jupiter's moon Io . When the gravitational force acting on a slope exceeds its resisting force, slope failure (mass wasting) occurs. The slope material's strength and cohesion and the amount of internal friction between material help maintain the slope's stability and are known collectively as the slope's shear strength . The steepest angle that a cohesionless slope can maintain without losing its stability is known as its angle of repose . When a slope possesses this angle, its shear strength perfectly counterbalances the force of gravity acting upon it. Mass wasting may occur at a very slow rate, particularly in areas that are very dry or those areas that receive sufficient rainfall such that vegetation has stabilized the surface. It may also occur at very high speed, such as
