Can you please explain to me the formation of a gorge of recession? I know that it has something to do with waterfalls but thats about it.

Thanks in advance

Basically, a waterfall forms through certain processes (which I'm happy to explain if you want?). Once a waterfall is formed, you're left with harder 'cap' rock on top of softer rock. The plunge pool churns around the eroded material and erodes/undercuts the soft rock behind it - this is mainly abrasion, they like it when you talk about specific processes of erosion. Once the soft rock has been undercut, the hard rock above it overhangs and eventually collapses under its own weight. This process repeats itself and the waterfall retreats upstream, leaving a gorge of recession from its original to its current position from the rock it has eroded.

Hope this helps
