More explanation about mass movement and slope stability
This video explains more on the variety of processes exist by which materials can be moved down a slope. these processes are known as mass movement or mass wasting.

Mass movement and Slope Stability
Mass wasting occurs when a slope fails : A slope fails when it is too steep and unstable for existing materials and conditions. Slope stability is ultimately determined by two principal factors: the slope angle and the strength of the underlying material. How does mass movement affect slopes? Steep and unstable slopes are more likely to have a mass movement than gentle and stable slopes . A fall or topple happens when rocks and other sediments fall through the air and land at the bottom of a slope. Flows are a mixture of water, rock and sediment.
