They are prone to virtually any form of erosion, weathering and mass movement/wasting.
Mudflow is a type of erosion known as mass wasting, specifically when a large amount of mud and debris moves downhill due to gravity. This movement can be triggered by heavy rainfall or rapid snowmelt.
Mass wasting is not required for karst topography to form, as karst topography primarily results from the dissolution of soluble rocks like limestone, dolomite, and gypsum by groundwater. However, mass wasting processes can influence the development of karst features by altering the landscape and accelerating erosion.
Mass wasting / landslide.
This form of erosion is referred to as mass wasting or mass movement. It occurs when gravity pulls loose rock and soil downhill, causing landslides, rockfalls, and slumps.
The fastest form of erosion is typically considered to be mass wasting events such as landslides, rockfalls, or debris flows. These processes involve the rapid movement of large amounts of rock and soil downhill due to gravity, causing significant erosion in a short period of time.
Creep is a form of mass wasting caused by the gradual downhill movement of soil and rock material due to gravity. It typically occurs on gentle slopes over a long period of time, with the soil slowly shifting downslope in response to factors like frost heaving and expansion and contraction of the soil.
Slump is a form of mass wasting that involves the downward movement of a block of material along a curved surface. It is a type of erosion process as material is being transported downslope due to gravity.
erosion
A mudslide is a form of mass wasting, which is the downslope movement of rock, soil, and debris under the influence of gravity. While erosion typically refers to the gradual wearing away of the land surface by water, wind, or ice, mudslides involve the rapid movement of a large mass of saturated soil and debris down a slope.
erosion
The fastest erosion would occur from rapid flooding and fast, high load moving water. Mass wasting or landslides would also move large amounts of material quickly.
