- Costal Weathering and Erosion
- Weathering is the breakdown of rocks where they are.
- Hydraulic action occurs when the force of the water is so strong it breaks off the particles of the rocks.
- Corrasion is where the rocks scrape against the edges of the rivers causing the rocks to breakdown.
- Corrosion is where the riverwater dissolves the rocks
- Attrition is where the rocks bang into each other and break up into smaller fragments.
- Waves that carry out these erosional processes are called destructive waves.
- They have a very high frequency
- Are high and steep
- Thier backwash is more powerful than their swash; this means that the waves takes in materials from the coats.
- Wind makes more powerful waves that can be more destructive.
- Fetch - the greater the fetch, the bigger and more powerful the wave.
