15.2 What causes mass movements?

Fig 15.15

On a rocky slope, usually there are faults, joints, bedding planes, or some combination thereof. The fractured rock is stable if the friction along joints and bedding planes, and cohesive forces between blocks, is greater than the downslope component of gravity. When some part of this system changes, it becomes unstable and mass movement results.
