Answer
Hydraulic Action
Hydraulic action refers to the force of moving water impacting upon rock surfaces, causing dislodgement and erosion. This process is particularly effective in river and coastal environments where wave action can intensify the erosive impact.
Abrasion
Abrasion is a process where sediment and rock particles are worn away as they collide with surfaces. In coastal areas, it occurs as waves carry sand and pebbles that strike against cliffs, gradually eroding them over time.
