Q
What are the 4 stages that form a waterfall.
A
- Falling water and large boulders loosen and wear away the softer rock.
- The hard rock above is undercut as erosion of the soft rock continues.
- 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.
- Erosion continues and the waterfall slowly eats its way upstream, leaving a gorge behind.
