==Key Stage 4==
===Meaning===
A '''waterfall''' is a place where the course of a [[river]] is interrupted by a steep drop.
===About Waterfalls===
: '''Waterfalls''' are caused by a [[river]] flowing over an area of hard [[rock]] to an area of softer [[rock]]s. The hard [[rock]] is more difficult to [[erosion|erode]] than the soft [[rock]] causing a difference in the height of the [[River Bed|river bed]].
