Weathering is a form of erosion involving elements of the weather, e.g. chemical weathering like corrosion of limestone, and mechanical weathering like exfoliation in deserts and freeze thaw (frost shattering) in colder areas.
MASS MOVEMENT
When large amounts of rock become unstable they will collapse. The contributing factors are rock type and excess water.
- Slumping – large amount of rock will collapse along a line of weakness if the ground is saturated.
- Land-slide – unstable rock collapses (usually in sections)
-
Rotational slip – rock slides along a slip plane.
