Here's a bit more about them:

* Formation: They form when waves and currents deposit sand, gravel, or other sediment parallel to the shoreline. This happens over time, often during storms or periods of high energy.

* Appearance: Beach ridges can look like low, parallel mounds or ridges running along the beach. They can be quite long and continuous, or they can be short and discontinuous.

* Significance: They provide valuable information about past sea levels, storm events, and coastal processes. They also play an important role in protecting coastal areas from erosion.
