Waterfall is a natural phenomenon in which water, often in the form of rain or ice, flows down the face of a cliff or other mountains. The flow is not continuous and may be described as having a current or wave-like character. The term waterfall is used primarily in the context of the natural phenomenon, although it is also used in the context of man-made waterfalls, such as those found in water parks and swimming pools.
