Presentation transcript:

Waterfall & Plunge Pool

Formation of Waterfall 1. More erosion on less erosion while less erosion on resistant rock/differential erosion 2. erosion in terms of hydraulic action/vertical erosion is serious 3. vertical descent of water/waterfall is formed 4. the base of the waterfall is undercut by eddy movement 5. the base is widened and deepened, forming plunge pool

A resistant rock layer is dipping upstream

A vertical resistant rock layer
