Erosion is the geological process in which Earth's surface is worn down by natural forces like running water, wind, glaciers and waves. Erosion is a key factor in the formation of beaches because erosion moves sediment (sand) from one location to another. There are three major types of coastal erosion; hydraulic action, corrosion and corrosion.
Hydraulic action is when waves crashing against a headland causes erosion. Waves enter cracks in the rock and air is compressed into the crack by the force of the water being pushed by the wave. As the air is compressed it acts to erode rock. Blow holes are a common feature formed by hydraulic action.
Corrasion is when waves crash over rock shelves and create erosion. The wave action moves rock and
