Mass Wasting Flashcards
1
Q
Mass Wasting
A
Downslope movement of broken rock material by gravity
2
Q
Rockfall
A
Rapid movement of rock, frost wedging
3
Q
Slide
A
Rapid movement, slope failure
slump = rotational slide along a curved sliding plane
4
Q
Flow
A
High moisture
earthflow - no failed slope, slow
mudflow - failed slope, fast speed, high water content
5
Q
Creep
A
Slowest moving
entire slope involved
freeze-that pattern, wet-dry precipitation
solifluction - high lat, high elevation tundra landscapes - meltwater cannot penetrate permafrost and causes downhill soil to sag
6
Q
Denundation
A
overall effect of disintegration, wearing away, and removal of rock material
weathering - breakdown by atmospheric or biotic
erosion - wind, water, ice trans, removal, deposit soil
7
Q
Frost wedging, salt wedging
A
