- Water
- Erosion
- Hydraulic action: the sheer force of flowing water wshes away any loose materials on the bed and banks
- Abrasion/ Corrasion: stones carried in the river bed and banks, wearing them away. Sometimes stones get trapped in a dip, where they swirl around and create potholes.
- Solution/ Corrosion: the slightly acidic river water dissolves rocks made of calcium carbonate (CaCO3)
- Attrition: stones collide together and are broken down becoming smaller and rounder.
- Transport
- Traction: stones rolled along the river bed by the force of flowing water.
- Saltation: small stones are bonced along the river bed by flowing water.
- Suspension: Particles of silt
- Solution: some minerals dissolve in water. Limestone, for example, slowly dissolves.
