A waterfall is a place where water rushes down a steep ledge. The water flows from higher land of harder rock, then it falls down a big step of rock to lower land of softer rock where it will continue on its journey. Usually the lower land is in a gorge. Waterfalls are usually made when a river is young, in places where softer rock is underneath harder rock.
