River terraces mainly indicate which process?
Answer and explanation
Correct answer: River rejuvenation and renewed downcutting
River terraces are remnants of former floodplains left at higher levels after a river incises its valley. Rejuvenation, caused by uplift or a fall in base level, increases the river’s vertical erosion and makes it cut down into its former deposits. Therefore option D is correct. Marine abrasion, closed desert drainage, and stagnant ice do not produce fluvial terraces.
