Which feature may first form when sea waves erode a weak line in coastal rock?
Answer and explanation
Correct answer: Sea cave
When waves repeatedly attack a joint, crack, or other weak line in a coastal cliff, erosion enlarges the opening into a sea cave. Therefore option B is correct. With continued erosion, a cave may develop into an arch; roof collapse can then leave a sea stack and later a stump. A delta and loess are depositional features, while a sinkhole usually forms by subsurface dissolution or collapse.
