- Erosion, Transportation and Deposition
- Erosion
- Hydraulic action this is the force at which the cliff or river channel and breaks away particles of rock.
- Corrasion this is eroded rocks picked up by the water scrape against cliffs and river channel wearing it away
- Attrition this is where the eroded rocks picked up by the river smash into each other and making them break into small pieces. edges get rounded off.
- Corrosion this is where the rain water dissolves some types of rock
- Transportation
- Traction this is large particles like boulders are pushed along by the force of the river
- Saltation this is pebble sized particles getting bounced along the river bed by the force of the water
- Suspension this is when the small particles like silt and clay are carried along by the river
- Solution these are soluble material that are dissolved in the water and get carried along
- Deposition is when the river drops eroded material , this happens when the river slows down.
- also happens when the volume of the water in the river falls
- the amount of eroded material in the water increases
- the water is shallower for example on the inside of a bend
- the river reaches the mouth
- Erosion
