ESC 100 WCC - Exam 2 study guide
100% Accurate!!
Mass wasting - ANSWERSDownslope movement of soil, sediment, or rock under direct
influence of gravity
Creep - ANSWERSGradual downhill movement of soil or regolith
Mud flow - ANSWERSAlso called Debris Flow. Rapid type of mass wasting that involves
flow of soil and regolith containing a large amount of water.
rock slide - ANSWERSOccur when rocks of bedrock break loose and slide down a
slope
Head - ANSWERSArea where stream originates (?)
Mouth - ANSWERSPoint downstream where it empties into another body of water
Discharge - ANSWERSVolume of water flowing past a certain point in a given unit of
time. "Discharge, usually measured in cubic meters per second or cubic feet per
second, is determined by multiplying a stream's cross- sectional area by its velocity."
Cut bank - ANSWERSOutside of the meander zone
Point bar - ANSWERSinside of meander zone, where larger sediment is deposited
Springs - ANSWERS
Artesian wells - ANSWERS• When groundwater under pressure rises above the aquifer
with no pump.
Cone of depression - ANSWERSDrawdown decreases with increasing distance from
the well, creating a cone of depression
Porosity - ANSWERS- Pore spaces are holes in rock and soil
- Porosity = % of total volume of rock or sediment that consists of pore spaces
Sinkholes - ANSWERSmade by collapsed caves or subsidence
caves - ANSWERS
Sinking streams - ANSWERSDisappearing streams
