- The input to rivers in precipitation (rain, snow etc)
- The processes of a river are: Erosion >>> Transport >>> Deposition
- The outputs from rivers are physical features

#### **How do rivers shape the landscape?**

Below are ways that rivers change the landscape and a short description of each:

- Hydraulic action: Force of water on river bank undercuts and removes material.
- Corrasion: Rocks bounce against side and bottom of river and break off more material.
- Attrition: Rocks collide with each other and break up into smaller pieces.
- Solution: Dissolved material being carried along by the river.
- Suspension: Small particles carried along by the river.
- Traction: Particles carried along the river bed.
- Saltation: Bedload particles bounced along the river bed.
- Deposition: River slows and dumps material including silt.
