Ocean waves do most of their erosion?

Ocean waves primarily cause erosion through their constant motion and the force exerted upon coastal structures as they break against shorelines. The energy from waves can wear away rocks and sediment, leading to the formation of cliffs, beaches, and other coastal features. Additionally, the turbulent water can dislodge and transport materials, further contributing to coastal erosion. This process is intensified during storms, when larger waves can significantly increase erosion rates.
