What does a knickpoint in a river profile indicate?
Answer and explanation
Correct answer: A sudden change in gradient or base level.
A knickpoint is a sharp break in the longitudinal profile of a river, showing a sudden change in channel gradient. It may result from a fall in base level, tectonic uplift, resistant rock, or renewed erosion after rejuvenation, and waterfalls can occur at such breaks. Option B is correct; the other options describe depositional settings that do not define a river-profile discontinuity.
