Correct answers: storm waves and ocean currents.

- Storm waves erode beaches by delivering high-energy waves that remove sand.
- Ocean currents (including longshore currents) transport sediment away, causing erosion.

Dune vegetation helps stabilize sand (reduces erosion). Sandbars usually dissipate wave energy and can protect the beach. "Shifting shorelines" describe change (an effect), not a direct cause.
