what is erosion?
where rocks are worn away by natural forces
what is hydraulic action?
where water is forced into the cracks of the river banks and over time wears them away due to the pressure
what is abrasion?
where rocks and sediment carried by a river scrape and wear away the river bed
what is attrition?
where rocks and stones knock into each other and wear each other away
what is solution (erosion)?
where soluble minerals get dissolved from the banks
what is transportation?
the movement of material from one place to further downstream
what is traction?
where boulders roll along the river bed
what is saltation?
where pebbles bounce along the river
what is suspension?
where sediment is carried along by the river flow
