, Normal fault form in response to horizontal, tensional stresses that stretch or
elongate the rocks. T or F - ✔✔True
A(n) _____________ fault has little or no vertical movements of the two blocks -
✔✔Strike-slip
The _________________ in California is the boundary between the North
American and Pacific plates - ✔✔San Andreas strike-slip fault
How do freezing, thawing, wetting, and drying contribute to soil creep? -
✔✔The soil expands and contracts, lifting particles and dropping them a slight
distance downslope.
Which of the following statements concerning mudflows is not true? -
✔✔Mudflows deposit talus slopes.
Which of the following materials has the maximum sustainable slope angle as
determined by the angle of repose? - ✔✔Dry Sand
Where do the most rapid mass-wasting events occur? - ✔✔Rugged, geologically
young mountains
As an erosional process, how is mass wasting different from wind, water, and
ice? - ✔✔Mass wasting does not require a transporting medium; gravity is its
controlling force.
