What Is the Definition of "wave Erosion"?

"Wave erosion" occurs when the energy and pressure of waves combines with the chemical composition of water to erode rock and sand. Wave erosion is also known as coastal erosion and occurs not only in oceans, but also in other large bodies of water.

Large oceanic storm waves are powerful and produce as much as 2,000 pounds of pressure per square foot, explains About.com. With sand, which is much easier for water to erode than rock, an annual erosion cycle can develop, causing sand to be removed during one season and then later returned by the waves during another season.
