What is a Waterfall and How Is it Formed? Waterfalls materialize within youthful river systems, a result of a deep and narrow channel that accommodates their formation. Such natural wonders emerge within a river’s upper course, where a stratum of robust rock lies adjacent to a layer of more yielding stone.
waterfall, area where flowing river water drops abruptly and nearly vertically (see video). Waterfalls represent major interruptions in river flow. Under most circumstances, rivers tend to smooth out irregularities in their flow by processes of erosion and deposition.
Waterfalls commonly form where water rushes down steep hillsides in upland areas. They are typical of the upper valley but can be found in the rivers lower courses where the process of rejuvenation creates enough potential energy for vertical erosion to recommence closer to the mouth of the river.
A typical waterfall is the kind in which a stream or river leaps over the edge of the precipice and falls freely through the air until it hits the lower level of the streambed. The term for a giant waterfall is cataract.
