V-shaped stream valleys result from the downcutting of stream erosion and ________.
A) mass wasting on the valley sides
B) isostatic rebound
C) the topographic rule of V's
D) conservation of angular momentum

Question

Quizplus · Accepted Answer

V-shaped stream valleys are created through the process of downcutting by the stream, which erodes the valley floor and creates steep valley walls. Mass wasting on the valley sides, such as landslides and rockfalls, can also contribute to the V-shape of the valley by causing the slopes to become steeper and more tightly defined.
