Mass Wasting Flashcards
refers to the downslope movement of rock, regolith and soil under the direct influence of gravity
Mass Wasting
the maximum angle at which the material can remain stable
Angle of Repose
movement involves the freefall of detached individual pieces of any size

most often form on hillslides in humid areas during times of heavy precipitation or snowmelt
Earthflow
rapid flow of mud containing large amount of water
Mudflow
rapid flow of soil and regolith containing large amount of water
Debris Flow
fast, down slope sliding of largely unconsolidated materials
Debris Slide
fast downslope sliding of a block of rock
Rockslide
rapid flow of tephra containing large amount of water
Lahar
type of mass wasting that involves the gradual dowhill movement of soil and regolith
Creep
is a form of mass wasting that is common in regions underlain by permafrost
