(i) Hydraulic action: breaking waves or swash hit against the cliff shattering the rock. The force of breaking waves compress air into the cracks or joints in the cliff face. This enlarges the cracks and part of the rock breaks off.
(ii) Abrasion or corrosion: the rock fragments carried by the waves are used as a tool to erode the cliff as the waves break at the cliff face. The material carried by the backwash erodes the sea-floor.
(iii) Attrition: the wearing down of particles as they continuously hit against each other and coastal rocks or cliff, thus reducing in size.
(iv) Solution action: the solvent and chemical action weakens and removes the minerals found in the cliff and sea-floor where there are limestone rocks.
