Here are some specific types of erosion driven by gravity:
* Mass wasting: This is a general term for the downslope movement of rock, soil, and other debris under the influence of gravity. It includes various processes like landslides, slumps, creeps, and rockfalls.
* Soil creep: This is a slow, gradual movement of soil downslope, often caused by the expansion and contraction of soil due to freezing and thawing or wetting and drying.
* Rockfall: This is the rapid descent of rock fragments down a steep slope, often triggered by earthquakes, frost wedging, or other disturbances.
So, while gravity is a key factor in erosion, it's not a specific type of erosion itself. You need to consider the mechanism by which gravity causes the movement of material to determine the specific type of erosion.
