Most stream valleys have a V shaped cross section because ________.
A)water washing down the slope makes straight channels.
B)vegetation on the slopes forces this profile.
C)mass wasting of weathered rocks on the slope maintain an angle of repose slope.
D)none of the above

Question

Quizplus · Accepted Answer

The V-shaped cross section is a result of mass wasting of weathered rocks on the slope that maintains an angle of repose slope. The valley is eroded downwards by the stream's force, creating a V-shaped cut that widens and deepens over time due to the mass wasting of the slope. Water washing down the slope does not make straight channels, and vegetation on the slopes does not force this profile.
