Mass Movement
Mass movement describes the movement of rocks on a hill or cliff. These movements are caused by weathering, erosion, and gravity. Small changes over time can mean that a cliff's centre of gravity hangs over the sea, instead of over land.
Slides
- Slides are when material moves down a slope in a straight line.
Slumps
- Slumps are when a slip plane forms under the cliff. The cliff then slumps down in layers.
Rockfalls
- Rockfalls are when the cliff (materials) break and crumble down the cliff.
