Sea waves have a great erosive force. Consider the following statements regarding the functions of sea waves:

1. When the sea water loaded with rock fragments and sand attack the coastal rocks it is called abrasion.

2. The rock particles present in the water hit against each other and break into progressively smaller particles, the process is called attrition.

3. The rocks made up of limestone are subjected to solution action by the sea waves.

Explanation: Sea waves have a great erosive force. In their role of an erosional agent, they perform four functions. When the sea water loaded with rock fragments and sand attack the coastal rocks it is called abrasion. The rock particles present in the water hit against each other and break into progressively smaller particles. This process is called attrition. Thirdly the broadening of cracks and crevices in the cliffs along the coast due to the attack of the sea waves is called the hydraulic action. The rocks made up of limestone are subjected to solution action by the sea waves. All these processes help in the formation of new features on the coastal margins
