Which term refers to the circular movement pattern of water particles at the air-sea interface?

Explanation:
The circular movement of water particles at the air–sea interface is called orbital motion. As a wave passes, water particles at the surface move in near-circular paths, with the size of the orbit decreasing with depth. This makes “orbit” the best term for describing the pattern of motion. The other ideas describe something different: the sea is the body of water, the restoring force is what returns the surface to calm after a displacement, and sea state describes current wave conditions, not the actual motion pattern of particles.
