Types of erosion

?
Hydraulic Action (Side of cliff)
Cliff has spaces full of air. Water goes into gaps and compresses (squash) air causing rocks to break apart by exploding
1 of 5
Abrasion (Side of cliff)
The sediment is hurled at the cliffs, wearing it away
2 of 5
Solution (In water)
Water s acidic because if salt in it causing a chemical reaction, dissolving the rock
3 of 5
Attrition (In water)
Loose sediment is swirled in the water colliding with eachother, wearing it down unitl it is smooth, rounder and in smaller pieces
4 of 5
What is erosion?
Rocks/material break away from the cliff causing it to change the shape of the coast because of waves crashing, creating sediment
