Types of erosion
Hydraulic Action
Where the force of the water forces air into cracks in the rock, splitting it open over time.
Abrasion
Where rocks being carried by the sea get scraped or thrown at the seabed or a cliff, wearing it away.
Attrition
Where rocks get knocked against each other, making them smoother and rounder.
Solution
Where the water dissolves more soluble types of rock, like chalk.

Swash & Backwash
Swash is the movement of water onto the beach, depositing sediment and other material. Backwash is the movement of water away and off the beach, taking sediment back into the sea.
