D) A sea level rise was followed by stream downcutting.

Question

Quizplus · Accepted Answer

Entrenched meanders are formed when land uplift occurs, causing rivers that previously meandered across a flat landscape to cut down into the bedrock, creating deep, winding valleys. This process is a result of the land being raised, which increases the river's gradient, leading to increased erosion and downcutting into the landscape.
