Mass movement is defined as the downward movement of rocks and rock fragments downhill. This happens as a result of gravity. Many of these downward slides are also often caused by added pressure of some kind on the material.

Mass wasting, also known as slope movement, is the geomorphic process by which soil, regolith, and rock move downslope under the force of gravity.

Mass movement is the down slope movement of earth materials under the influence of gravity. The detachment and movement of earth materials occurs if the stress imposed is greater than the strength of the material to hold it in place.

Mass movement or mass wasting is movements of masses of bodies of soil, bed rock, rock debris, soil, or mud which usually occur along steep-sided hills and mountains because of the pull of gravity. This slipping of large amounts of rock and soil is seen in landslides, mud slides, and avalanches.

Mass movement is the movement of surface material caused by gravity. Landslides and rockfalls are examples of very sudden movements of this type. Of course geological agents such as water, wind and ice all work with gravity to cause a leveling of land.

Gravity, the driving force behind mass movement, pulls earth materials from higher elevations to lower ones. Earth materials typically exert some resistance to moving downslope; these efforts constitute resisting forces.
