Question

Quizplus · Accepted Answer

A nickpoint refers to a sudden change or interruption in a stream's graded profile of equilibrium due to changes in erosion patterns, often caused by changes in the underlying geology, tectonic activity, or human activities. Gradation refers to the process of erosion and deposition that shape a stream channel over time. Base level refers to the lowest point to which a stream can erode and usually refers to sea level or the level of a large body of water into which a stream flows. Longitudinal interruption is not a commonly used term in geomorphology.
