• Abrasion: When waves bring bits of stone and grind the rock, wearing it away, this is sandpapering effect.
• Attrition: When rock fragments carried by sea knock against each other causing them to be smaller and smoother.
• Solution: Water dissolves soluble particles by sea water, this is aided by acid in sea water.
