The Pacific Coastal Fog Project. There are two types of waves in the universe, electromagnetic (e.g., light waves) and mechanical (e.g., sound waves). The sea erodes the base of the cliff in a number of ways: •Hydraulic action – This is where erosion occurs due to the pressures exerted by breaking waves as air trapped in cracks in the cliff is compressed by the water. They form when the coastline suddenly changes direction and longshore drift carries sediment out of land and into the sea. A sound is a marine geographic formation, which is located along coastlines around the world. It is listed as a World Heritage Site. A wave that has weak swash and strong backwash, larger in height.
