- River water dissolving soluble minerals and carrying them away.
hydraulic Action
- Erosion by the force of river water when it thrusts itself into cracks and joints of rocks on the sides of
the channel dislodging lumps.
- Also by pushing air into the cracks, compressing it increasing pressure which widens the cracks
eventually dislodging lumps.

Abrasion/Corrasion
- Abrasion is scratching of the bed and banks by materials are carried away by the river.
- Corrosion is hurling of rock fragments carried by the river against rocks which weaken and eventually
break them.

Attrition
- Hitting against one another of rock fragments carried by river water breaking one another into smaller
pieces.
