The significance of mass wasting processes can be seen in that most river valleys are broad rather than "V shaped" because mass wasting slope failures exceed stream erosion.

Question

Quizplus · Accepted Answer

Mass wasting processes can result in the gradual downslope movement of soil, rock, and debris, which can create gentle slopes that are more susceptible to erosion by streams. Thus, over time, mass wasting processes can contribute to the development of broad river valleys. In contrast, streams typically erode narrow, "V-shaped" valleys through the landscape. Therefore, the statement that "mass wasting slope failures exceed stream erosion" is generally true and illustrates the significance of these processes in shaping the landscape.
