Resource summary
Erosion in Rivers
Hydraulic Power
The force of the water on beds + banks of rivers
Powerful when there is a flood
It powers most of the types of erosion in rivers
Corrasion/Abrasion
Pebbles + boulders being carried along by the river
It erodes the bed + bank away
Corrosion
Sometimes river water is slightly acidic and it can dissolve rocks over a period of time
An example of this is the dissolving of limestone
We get calcium hydrogen carbonate
Attrition
Pebbles banging into each other powered by hydraulic power
This causes the pebbles to eventually break
