A waterfall is typically a physical formation resulting from water, frequently in the form of a stream, flowing over an erosion-resistant rock formation that forms a nickpoint, or unexpected break in elevation.

Some waterfalls form in mountain environments in which the erosive water force is elevated and stream courses may be subject to sudden and catastrophic change. In such cases, the waterfall may not be the end product of many years of water action in excess of a region, but rather the result of moderately sudden geological processes such as landslides, faults or volcanic action. In cold places, snow will build up in winter and melt and twist into a waterfall in summer. Water falls can be cool.
