Traction (Transportation)

Large particles such as boulders are pushed along the river bed by the force of the water

1 of 8

Saltation (Transportation)

Pebble-sized particles are bounced along the river bed by the force of the water

2 of 8

Suspension (Transportation)

Small particles such as silt and clay are carried along by the water

3 of 8

Solution (Transportation)

Soluble materials dissolve in the water and are carried

4 of 8

Hydraulic action (Erosion)

The force of the water breaks rock particles away from the river channel

5 of 8

Abrasion (Erosion)

Eroded rocks picked up by the river scrape and rub against the channel, wearing it away

6 of 8

Attrition (Erosion)

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. The further material travels, the more eroded it gets- particle size decreases between source and mouth

7 of 8

Solution (Erosion)

River water dissolves some types of rock, e.g chalk and limestone
