Waves are never pure water. They contain salt and other minerals. These mineral particles hitting rock with the force of the wave behind it has the effect of millions of tiny chisels striking. Each individual strike does little damage, but over time, the cumulative effect is erosion.
Rigorous erosion of sea floor takes place in the surf zone, (i.e. between shoreline and breakers.) Waves can both erode rock and deposit sediment. Because of the continuous nature of ocean currents and waves, energy is constantly being expended along coastlines and they are thus dynamically changing systems, even over short (human) time scales. waves can only erode if the water along a coastline is shallower than 1/2 times the wavelength. But, when the wave breaks as it approaches the shoreline, vigorous erosion is possible due to the sudden release of energy as the wave flings itself onto the shore.
by the rubbing of the minerals that are in the water, also have you ever rubbed sandstone same principal, rock is not just one piece it is many tiny particles called elemnts that have a tendecy to bond wiht the minerals in the water, and be removed.
