Rounded holes in a river bed are known as what?
Answer and explanation
Correct answer: Potholes
Potholes are rounded depressions drilled into a river bed by abrasion. During high flow, pebbles and other hard fragments become trapped in small hollows and are rotated by swirling water. Their grinding action enlarges the hollows into circular or cylindrical holes. Therefore, option A is correct. A spit is a coastal depositional feature, a barchan is a crescent-shaped wind dune, and a moraine is glacial debris.
