The degradation of a landscape by weathering, erosion, and transportation will ultimately reduce the landscape down to

C) the mountain tops.
D) valley level.

Question

Quizplus · Accepted Answer

Base level is the lowest level to which a stream or river can erode its channel. A landscape that undergoes weathering, erosion, and transportation will eventually reach its base level, where erosion ceases, and the landscape becomes a plain or a relatively flat area. The continental shelf is a shallow underwater area, and mountain tops are the highest points on a landscape and do not necessarily result from degradation by weathering and erosion. The valley level may be a temporary state of the landscape, but it does not always represent the final outcome of degradation.
