What are the higher remnants of old floodplains along a river valley called?
Answer and explanation
Correct answer: River terrace
A river terrace is a step-like surface left beside a valley when a river cuts downward into its former floodplain. This renewed vertical erosion may follow uplift, a fall in base level, or greater stream energy. The abandoned floodplain remains higher than the present channel. A beach is coastal, a barchan is a crescent dune, and a drumlin is a glacial hill, so option C is correct.
