When does an offshore bar form?
Answer and explanation
Correct answer: When waves deposit sand away from the shore as a submerged ridge
An offshore bar is a submerged or partly submerged ridge of sand and gravel that forms seaward of the beach. Wave action and nearshore currents transport sediment and deposit it where water depth and energy conditions favour accumulation. Option D correctly describes this coastal depositional process. Gorge cutting, yardang formation, and cirque excavation are produced by rivers, wind, and glaciers respectively.
