Slumping – Rapid mass movement which involves a whole segment of the cliff. Movement is characterised by sliding along a slope, which can be concave or straight, when land is saturated
Note: Slumping most frequently occurs after removal of a slope base. This can be due to storm wear erosion and road construction.
My Mum slumped (slumping) into the chair. She was a mass movement sliding into a curve.
A slump is a type of mass movement that happens when a mass of loosely consolidated materials or a rock layer moves a short distance down a slope.
The cut which forms as the landmass breaks away from the slope is called the scarp and is often cliff-like and concave (curved inwards).
