Coastal erosion - is the gradual wearing away of material from a coast by the action of the seawater.

Abrasion - When waves break against the cliff they fling rocks and pebbles at it which wear away the cliff like sandpaper

Attrition - Rocks and boulders crash together in the waves breaking and wearing down into smaller pieces eg pebbles…
