Where are rapids more common in a river?
Answer and explanation
Correct answer: In areas of hard rocks and irregular slope
Rapids are stretches where river water flows swiftly and turbulently over an uneven bed. Resistant rock ledges, sudden changes in gradient, and irregular channel levels interrupt smooth flow and increase turbulence. Therefore option D is correct. Calm deltaic water encourages deposition, while a beach and a cave roof are not river-channel settings where rapids form.
