Where is mass wasting most likely to occur?
Mass wasting, also known as slope movement or mass movement, is the geomorphic process by which soil, sand, regolith, and rock move downslope typically as a solid, continuous or discontinuous mass, largely under the force of gravity, frequently with characteristics of a flow as in debris flows and mudflows. 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 hundreds of years. Mass wasting occurs on both terrestrial and submarine slopes, and has been observed on Earth, Mars, Venus, and Jupiter's moon Io.

Soil and regolith remain on a hillslope only while the gravitational forces are unable to overcome the frictional forces keeping the material in place (see slope stability). Some factors that reduce the frictional resistance relative to the downslope forces, and thus can trigger slope movement, can include:

earthquakes
increased overburden from structures
increased soil moisture
reduction of roots holding the soil to bedrock
undercutting of the slope by excavation or erosion
weathering by frost heave or chemical dissolution
bioturbation

Mass wasting is a process where by which soil, sand, regolith, and rock move downslope. Mass wasting occurs when the gravitational force acting on a slope exceeds its resisting force. It can occur on both terrestrial slopes and submarine slopes but is most likely to occur in places with a lot of earthquakes, increased soil moisture, and erosion.
