- Waterfall
- 1. Falling water and boulders loosen and wear away the softer rock
- 2. The hard rock above is undercut as erosion of the soft rock continues
- 3. The hard rock collapses into the plunge pool to be broken up and washed away by the river
- The position of the falls moves back
- 4. Erosion continues and the waterfall slowly eats its way upstream, leaving a gorge behind
