Beach erosion can be caused by several factors, including:
1. **Ocean Currents**: These can transport sediment away from the shore, leading to erosion over time.
2. **Storm Waves**: Intense waves generated by storms can erode beaches by removing sand and sediment from the shoreline.
3. **City Building Structures**: Infrastructure such as jetties, seawalls, and buildings can interfere with natural sediment transport processes, often exacerbating erosion in adjacent areas.
4. **Sandbars**: While sandbars typically act as a buffer to reduce wave energy hitting the shore, they can also contribute to erosion under certain conditions, such as if they are formed improperly or are altered by human activity.
In summary, all of the options listed can contribute to beach erosion, but ocean currents and storm waves are particularly significant natural causes, while city structures are a major human-influenced factor.
