Quizplus · Accepted Answer

Entrenched meanders are formed by meandering rivers that have carved into the land due to uplift or falling base level. As the river cuts down into the substrate, it forms a deeper and narrower channel, leaving behind high walls or cliffs on either side. This process is called incision, and it results in an entrenched meander. Option A is incorrect because rising seas would not cause a meandering river to become entrenched. Option B is incorrect because sediment deposition would fill in the meander, making it less entrenched. Option D is incorrect because one of the previous choices must be correct.
