A point along a river or stream where water descends abruptly over a vertical or near-vertical drop, typically formed where the channel crosses a band of resistant rock that erodes more slowly than the softer rock immediately downstream. A waterfall's plunge continually undercuts the rock at its base, causing the falls to migrate slowly upstream over time as the resistant cap rock is eroded away.

Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling onto softer rock, which erodes faster, leading to an increasingly high fall.
