-------------------------erosion below-------------------------------

Hydraulic action: The physical force of the moving water wears away and breaks off rock and soil from the banks and bed of the river.

Abrasion: Small stones carried by the river wear away and break off rock along the riverbed and banks by hydraulic action colliding with them. This causes them to break down further.

Attrition: The small stones in the river are worn down and broken up as they hit off each other.

Solution: Rocks such as limestone, and soil are dissolved by acids in the water.

-------------------------------transportation below-------------------------------

Traction: The larger stones are rolled along the bed of the river.

Saltation: The smaller pebbles are bounced along the bed of the river.

Suspension: Light materials such as sand and silt float along in the water.

Solution: Other materials dissolve in the water and are carried along by the river.

-------------------------------deposition below-------------------------------

Causes of deposition include:

* Reduction in the river's speed: This can happen when a river enters a lake or the sea or during a period of dry weather.

* Increase in load size: This can happen when a tributary joins a river or after a period of heavy rainfall. The river does not have the energy to carry its increased load so it drops it.

* reduction in the river's volume: This can happen during a period of dry weather.

* Levelling off of gradient: This occurs when the river reaches flatter land.
