How do waves cause erosion and deposition?
Waves cause erosion and deposition in several ways.
As waves reach shallow water near the ocean shore, they begin to break. As the breaking waves hit the shoreline, their force knocks fragments off existing rock formations.
Another way waves causes erosion is by forcing water into cracks in the rocks at the shoreline.
And in Deposition, waves carry large amounts of sand, rock particles and pieces of shell. At some point, waves deposit the material they carry.
