| Frage | Antworten |
| Abrasion | Eroded rocks are picked up by the river bed and they scrape and rub against the channel. Most erosion happens this way. |
| Hydraulic Action | The force of the water breaks rock particles away from the channel |
| Solution | The river dissolves some rocks - for example, chalk and limestone. |
| Attrition | Eroded rocks smash into each other and break into smaller parts. |
| Solution | Soluble materials are dissolved and carried along in the river |
| Saltation | Pebble sized particles are bounced along by the water's force |
| Suspension | Small particles like silt and clay are picked up and carried along with the river |
| Traction | Large particles (such as boulders) are pushed along by the river's force |
| Deposition | A river drops eroded material. It usually happens when a river loses velocity. |
