cross sections show low friction bedding planes parallel to the hillside. Water percolates into rock along joints.

15.3 What factors determine slope stability?

Fig 15.19

Joints, faults, bedding planes, or any planar feature that interrupts cohesion is a risk for slope instability. Water will preferentially travel down such features, weakening them by reducing resisting forces and by weathering the minerals therein. Chemical and physical weathering play roles in slope destabilization.
