- River Processes (TED)
- Erosion
- is the wearing away of rock & soil found along the river bed & banks
- also involves the breaking down of the rock particles being carried downstream by the river
- Hydraulic action
- the force of river against the banks that can cause air to be trapped in cracks & crevices
- pressure weakens the banks & gradually wears it away
- the force of river against the banks that can cause air to be trapped in cracks & crevices
- Abrasion
- rocks carried along by the river wear down the river bed & banks
- Attrition
- rocks being carried by river smash together & break into smaller, smoother & rounder particles
- Solution
- soluble particles are dissolved into the river
- is the wearing away of rock & soil found along the river bed & banks
- Transport
- is when rivers pick up & carry material as they flow downstream
- Solution
- minerals are dissolved in the water & carried along in solution
- Suspension
- fine light material is carried along in the water
- Saltation
- small pebbles & stones are bounced along the river bed
- Traction
- large boulders & rocks are rolled along the river bed
- Deposition
- when material in the river is dropped & it will drop the heaviest first
- Erosion
