How do waterfalls form gcse
WebWaterfalls are formed as the river flows downstream. The river can flow over different rocks- some are hard and some are softer. As water flows it erodes the rocks. However, it erodes layers of softer rock more quickly and easily than the layers (or strata) of harder rock. WebWaterfalls form when a river flows over an area of softer rock after flowing over an area of harder rock. Due to the softer rock being more easily eroded than the harder rock, the soft rock undercuts the harder rock. The hard rock is left overhanging and due to continual erosion and the force of gravity, eventually collapses.

WebA waterfall is an erosional landform, which occurs where there is a layer of hard rock on top of a layer of softer rock.
