Mass wasting -What is mass wasting? -When does mass wasting occur? -driving forces (gravity) -resisting forces (friction) -Where does mass wasting occur? -Controls and triggers of mass wasting (know how each of the following affects mass wasting) -Over-steepened Slopes -angle of repose -Excess Water -Earthquakes -Added Weight -Vegetation Removal (fires, logging/deforestation, constructions projects, etc.) Pre-existing planes of weakness in bedrock examples: sedimentary bedding planes, metamorphic foliation, fractures in any rock type -What do we (humans) do that contributes to mass wasting? -Types of mass wasting [for each type you should know: speed, slip plane (shape and/or angle), Earth materials involved, and the role of water] -creep (most widespread and costliest) -slumps -slides -falls -debris flows (mudflows)Explanation / Answer
Mass wasting is a movement of slop on hills and mainly occurs on high elevated area.
These forces are mainly driven by gravitational forces on high elevated areas.
Mass wasting occurs on high elevated regions.
These mass wasting are frequently affected by excess of water, earthquakes, added weight.etc.
