Waterfall is a place where water flows over a vertical drop in a river or stream. The water falls from a higher level to a lower level, often creating spray and mist. Waterfalls can be small or very large, depending on the height and amount of water. They are often found in areas with uneven land.

Waterfalls are found around the world in rivers and streams where there are changes in elevation. They form over time as water moves across different layers of rock. Waterfalls are part of natural landscapes. They support surrounding ecosystems with plants and animals nearby.
