The maximum slope angle that allows rock, sand, clay, and debris to stay in place without movement is called:
A)angle of incident
B)gravity
C)downslope erosion
D)angle of repose

Question

Quizplus · Accepted Answer

The angle of repose is the maximum slope angle at which loose material, such as rocks, sand, clay, and debris, can remain in place without sliding down. This is due to the balance between the gravitational force pulling the material downhill and the frictional force holding it in place.
