What is a waterfall erosion retreat?
Quick Answer
Waterfall erosion retreat is the upstream movement of a waterfall caused by erosion at its base. As the rock is undercut and collapses, the waterfall shifts backward.
The Full Story
A waterfall does not stay fixed in place forever. The falling water erodes the rock at the base, creating a plunge pool and undercutting the cliff face. Eventually, sections of rock collapse, and the waterfall moves slightly upstream. This process can reshape valleys over thousands of years and helps explain why waterfalls often migrate away from their original location.
Key Facts
1.Waterfalls can move upstream over time
2.Caused by undercutting and rock collapse
3.Driven by erosion at the base
