Quizplus · Accepted Answer

A nickpoint is an interruption in a stream's graded profile of equilibrium. It is a point where there is a sudden break in slope and a stream moves rapidly over a hard rock layer or some other obstacle. The stream then erodes the rock layer upstream rapidly, causing a knickpoint that moves upstream over time.
