Lesson details
Key learning points

- There are four types of transportation: traction, solution, suspension and saltation.
- Deposition occurs when the river has lost its energy and can no longer carry its load.
Keywords
Erosion - the process by which Earth’s surface, e.g. rock or soil, is worn away and transported from its ordinal state and original location
Transportation - where rivers move sand, mud and rocks
Deposition - when sand, mud and rocks are dropped by the river
Common misconception
Attrition is where rocks and sediment carried by the river collide with the bed and the banks causing pieces to break off.
Abrasion is where rocks and sediment carried by the river collide with the bed and the banks causing pieces to break off.
