Here's a breakdown:

* Mass wasting is a general term for the downward movement of rock, soil, and debris under the influence of gravity.

* Mass movement is another term for the same phenomenon.

It encompasses various types of movement, including:

* Creep: Slow, gradual movement of soil and rock downhill.

* Slumps: Rotational movement of a mass of soil or rock along a curved surface.

* Slides: Movement of a mass of soil or rock along a planar surface.

* Flows: Rapid movement of a mass of soil or rock mixed with water, such as mudflows and debris flows.

* Falls: Free fall of rock or debris from a cliff or steep slope.
