Study Notes
Mass Wasting
- Mass wasting is the action of gravity as a geomorphic agent
- Common terms for mass wasting events are landslides, but this is not a technical term
- Mass wasting can be triggered by various events like heavy rain, snowmelt, earthquakes, and forest fires, but not always a large event
- Maximum steepness of the hillside/mountain is called angle of repose. When hillside/mountainside steepness exceeds angle of repose, gravity moves regolith downward until angle of repose is restored
- Different types of mass wasting events exist, including falls, slides, flows, and creeps
- A fall is the fastest type, followed by slides and flows
- Creep is the slowest type, can be glacier-related (solifluction)
- Mass wasting events can involve various materials like rock, debris, earth, or mud
- Avalanche can be rock, mud, or a glacier-related snow avalanche
- Accumulation of sediment from mass wasting events can create talus slopes or escarpments - steep cliffs at the base of a slope
