Drawing to show regolith, rupture surface and the underlying bedrock.

15.2 What causes mass movements?

Fig 15.16

In the case of regolith, much of the resisting force is in the cohesion and friction between particles, as well as the friction and cohesion between the regolith and the bedrock surface below. When particles lose contact with one another, the bulk resistive force is effectively gone and movement results.
