Once the original rock has been broken up by weathering and soil formation, it is now an unconsolidated mass of
small fragments which can make its way downhill under the influence of gravity, very much assisted by water.
Some of the processes of mass movement occur steadily but gradually.
Other processes which occur on a regular basis include
Other processes which happen only occasionally, but then with greater impact on the land (and in the media),
include
- mud flows

In these various ways, the 'hillside' makes it way down to the river or glacier so that the weathered material
can be tranported on the next part of its route. The hillside is lowered as the once-solid rock is removed, and new
rock is exposed to the action of weathering.
