Coastal Definitions

“Rock on rock” - Particles carried by the waves crash against each other and are broken up into smaller particles.

“Rock on cliff” - Particles carried by the waves crash against the cliffs, eroding the cliffs

“Rusting / dissolving” - Salt in the seawater slowly dissolves the cliffs. - The material produced is carried away by the process of solution.

- “Pressuring”- The water traps air in cracks and caves in the rock. - This air is compressed by the incoming waves placing great pressure on the rocks, causing them to crack eventually.
