Quick Summary

A beach cusp is a geological formation consisting of sand and gravel deposits that are shaped by wave action into points projecting seaward along a coast. These formations are a type of coastal landform, influenced by processes such as waves, currents, and tides. The term "cusp" itself refers to a point or apex, and in a geological context, it describes these projecting points on a coastline. The formation and persistence of coastal features like beach cusps are a result of various forces acting on the coastal zone, including wave energy and tidal ranges.123
