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. This goes on continuously causing the waterfall to retreat upstream. A Fall in Sea Level.
