- Geography: Methods of erosion.
- Hydraulic action
- The sheer force of water hitting the bed and banks of the river causes erosion to take place.
- Pieces of the rocks break off and stones become smaller in size
- The sheer force of water hitting the bed and banks of the river causes erosion to take place.
- Abrasion
- Occurs when the load the river is carrying hits against the river beds and banks.
- Materials break off into pieces
- Attrition
- Happens to stones and boulders in the river
- When the stones and boulders knock against each other they are weakened over time
- This causes pieces to break off and reduce in size
- solution
- Occurs with rock types such as chalk and clay
- Soluble rocks are dissolved in the fast flowing water
- Hydraulic action
