How does hydraulic action help in sea cave formation?
Answer and explanation
Correct answer: Wave pressure compresses air and water in cracks and breaks rock
Hydraulic action occurs when waves force water and air into joints, cracks, and faults in a coastal cliff. Repeated compression and release increase pressure on the crack walls, while wave impact can remove loosened fragments. The opening therefore enlarges into a cave, particularly along weak zones. Option A gives this mechanism; loess, till, and drumlins belong to different geomorphic environments.
