Quizplus · Accepted Answer

Entrenched meanders are formed due to the erosion and downcutting of a meandering river into the surrounding landscape, usually in response to uplift or a fall in base level. The river cuts deeper and migrates laterally, leaving behind a winding ridge or hill called a "meander scroll." Over time, these scrolls become separated from the river channel, forming entrenched meanders. A and B are not applicable as they refer to processes that do not result in the formation of entrenched meanders.
