- Coasts
- Waves
- Formed by the movement of the wind over the surface of the water causing friction
- Swash- movement of wave up beach
- Backwash- movement of wave back down beach
- Underlow- water moves back down beneath the water's surface
- Strong wave
- 1. wind is stroger
- 2. wind blows for longer
- 3. larger fetch
- Constructive waves
- strong swash, weak backwash
- gentle- associated with summer/ calm
- lower energy
- Debree deposited on beach
- lower energy
- gentle- associated with summer/ calm
- Destructive waves
- Quite strong swach, stronger backwash
- cliff attacked, eroded material removed by wave
- Less beach to absorb wave energy- process continues
- cliff attacked, eroded material removed by wave
- Quite strong swach, stronger backwash
- strong swash, weak backwash
- The coastal system
- 1. Erosion and weathering
- 2.Transportation
- 3. Deposition
- Depositing material, building new land
- Movement of material
- 3. Deposition
- erosion- rocks disintegrated by movement
- weathering- disintegration without movement
- 2.Transportation
- 1. Erosion and weathering
- Erosion processes
- Abrasion
- waves throws debree at cliff face- over time, wears away
- Attrition
- material in waves collide with one another as breaks on beach
- Hydraulic Action
- airs compressed into gaps in cliff- air released explosively
- Abrasion
- Weathering
- 1.Corrosion(solution)
- 2.salt crystals
- 3.wetting and drying of clay

- Economy/ jobs eg. fishing and tourism
- eg. blackpool
- Industry eg. ports and boat yards
- Portsmouth
- Flat land- easy to build on
- Coasts
