Coastal Processes
1. I can explain how the sea erodes the landscape by the processes of:
1. Hydraulic Action
2. Abrasion
3. Attrition

Coastal Processes of Erosion
Hydraulic action – force of the waves crashing against the shore and cliffs forces air into cracks in the rock (1), causing the air to implode, the shockwave erodes the rocks (1).
Abrasion – wearing away of cliff by sand, shingle and pebbles (1) hurled against them by waves (1).
Attrition – waves cause eroded material to smash against each other (1). Gradually the eroded material becomes smaller and rounder aiding abrasion (1).
Solution – dissolving of certain rock types (1) by the naturally occurring acid and salt in the sea water (1).

Coastal Processes of Deposition
1. I can explain how the sea shapes the landscape by the processes of:
1. Longshore Drift
1. Longshore Drift
Coastal Processes of Deposition
Longshore Drift
The swash moves up the beach at an angle (1) due to the direction of the prevailing winds (1).
The backwash moves back down the beach at a right angle (1) due to gravity (1).
