Question

Quizplus · Accepted Answer

An abrupt increase in stream gradient over a short distance creates a knickpoint, which can result in the formation of waterfalls and rapids. Option B, an escarpment, is a steep slope or cliff formed by erosion or faulting, not necessarily related to stream gradient. Option C, a slot canyon, is a narrow canyon formed by water erosion in a desert environment, again not necessarily related to stream gradient. Option D, a V-shaped valley, is a valley carved by a river with a relatively constant gradient over a longer distance, not an abrupt increase in gradient over a short distance.
