- Erosion
- Hydraulic Action
- The force of the water breaks rock particles away from the river channel
- Attrition
- Eroded rocks picked up by the river smash into each other and break into smaller fragments
- Their edges also get rounded off as they rub together
- Abrasion
- Eroded rocks picked up by the river scrape and rub against the channel, wearing it away
- Most erosion happens by abrasion
- Solution
- Water dissolves some types of rock
- eg. chalk and limestone
- Hydraulic Action
