- Erosion of the Coast
- The Fetch
- The fetch is the distance that the wave has travelled between lands
- Affected by the prevailing wind
- Bays and Headlands
- Cordant coastline
- Causes rounded bays
- Rocks are parallel
- Discordant coastline
- Alternative bands of rock
- Rock bands at 90 degrees to coast
- Differential erosion
- Soft rock is eroded by the waves
- Hard rock is then eroded away as it has a large surface area
- Cordant coastline
- Erosion
- Erosion of rocks
- Transport
- Rocks are moved along the beach. Prevailing wind causes the material to move in a zig-zag pattern. Bachwash caused by gravity.
- Deposition
- Rocks are placed in a spit shape at the end of the beach.
- Erosion of a Headland
- 1. Crack - Erosion of rocks.
- 2. Cave - Cordant coastline
- 3. Arch - Erosion of weak cave rock
- 4. Stack - Unssupported rocks falling
- 5. Stump - Erosion

- Cliff Formation and Wave Cut Platform
- This process is continuous and will repeat over and over again.
- A notch is formed and unsupported rocks fall into the sea.
- A cliff face forms and the cliff is retreating as a new notch is being formed. The sea carries away fallen rocks.
