What are the 3 ways in which waves erode rocks?

Waves erode rocks primarily through hydraulic action, abrasion, and solution. Hydraulic action occurs when waves crash against rocks, creating pressure that can fracture them. Abrasion involves the grinding action of sediment and rocks carried by waves, which wear down surfaces over time. Solution occurs when seawater chemically reacts with minerals in the rocks, dissolving them and contributing to erosion.
