Under what condition is an incised meander formed?
Answer and explanation
Correct answer: When a meandering river downcuts after rejuvenation.
An incised meander forms when a river that already follows a looping meandering course gains renewed erosive power and cuts downward into its former valley floor. This commonly follows rejuvenation caused by a fall in base level or tectonic uplift. Option C is correct because the old bends are preserved while the channel becomes deeply entrenched. Wind deposition, coral growth, and cave calcite involve unrelated processes.
