The input to rivers in precipitation (rain, snow etc)

The processes of a river are: Erosion >>> Transport >>> Deposition

The outputs from rivers are physical features

How do rivers shape the landscape?
Below are ways that rivers change the landscape and a short description of each:

Hydraulic action:
Force of water on river bank undercuts and removes material.

Corrasion:
Rocks bounce against side and bottom of river and break off more material.

Attrition:
Rocks collide with each other and break up into smaller pieces.

Solution:
Dissolved material being carried along by the river.

Suspension:
Small particles carried along by the river.

Traction:
Particles carried along the river bed.

Saltation:
Bedload particles bounced along the river bed.

Deposition:
River slows and dumps material including silt.
