I’ve read that Niagara Falls erodes backwards towards Lake Erie at a rate of 3 feet per year. This means that in a few hundred, maybe thousand (maybe even longer), the falls would have eroded all the way to Lake Erie. What will happen when it does? Will the lake’s floor begin to erode as well or will the water even out? I can’t wrap my head around it.

it will erode back about 4 miles then it will stop being falls and just be some rapids that connect the two lakes.
the lip of the falls is a hard stone that is tilted to the south. And the erodes upstream, it also gets lower. Eventually it will erode and just be part of the river bed.
