Erosion, Transportation + Deposition definitions

Question	Answer
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.
