Waterfall Formation
Waterfalls form where the river bed has a layer of harder rock overlying the softer rocks.
- As water falls the softer rock is eroded much more quickly than the harder rock; therefore undercutting the harder rock.
- The hard, overrhanging rock eventurally collapses.
- The collapsed rocks fall into the plunge pool causing more erosion of the soft rocks and a deeper plunge pool.
- This goes on continuously causing the waterfall to retreat upstream.
- The waterfall leaves a steap sided gorge as it reatrets.
Waterfalls may also be caused as a result of: - Glacial Erosion
- A Fall in Sea Level
- Earth Movement
