Answer

1. Hydraulic Action

The erosive force of water in breaking waves as they strike the coast causes significant erosion. Rapidly moving water can exert pressure on rock surfaces, leading to their disintegration.

2. Abrasion

This process involves the force of rocks and stones being carried by waves and hurling them against the coast. The impact of these materials can wear down the coastal rock, contributing to erosion.
