The hard rock is left overhanging and because it isn't supported it eventually collapses
The fallen rocks crash into plunge pool and swirl a road causing more erosion
Overtime this is repeated and the waterfall moves upstream therefore forming a sloop-sided
gorge as the waterfall retreats
(ii)Formed where a river channel passes over underlying hard rock
