The two correct answers that can cause beach erosion are:
1. **Storm waves** - Strong waves generated during storms can erode beaches by washing away sand and weakening the coastal structure.
2. **Ocean currents** - Persistent ocean currents can also contribute to beach erosion by transporting sand away from the shore.
Dune vegetation can actually help prevent erosion, while sandbars typically serve as protective structures against wave action. Shifting shorelines can be a result of erosion, but they are not a direct cause.
