The Work of Rivers

How Rivers Erode

Hydraulic Action This is the force of moving water,which breaks fragments from the bed and the banks (sides) of the river. The material carried along the river is called its load
Abrasion When the load hits against the bed and banks of the river and erodes them rapidly. Abrasion is the most powerful way in which rivers erode
Attrition The stones carried in the load of a river are themselves worn down. Stones are smoothened, rounded and made smaller by the process of attrition
Solution Chemicals in the water help to break down some rocks. Carbonic acid, for example, slowly dissolves limestone
