How Are Waterfalls Formed? - WorldAtlas

WebWaves are created by the action of the wind blowing over the sea or ocean. The friction from the wind causes the surface water to move in ripples which eventually form full waves. The stretch of ocean water over which the wind blows is called the FETCH. WebWaterfalls are formed as the river flows downstream. The river can flow over different rocks- some are hard and some are softer. As water flows it erodes the rocks. However, it erodes layers of softer rock more quickly and easily than the layers (or strata) of harder rock. WebOne technique used is to encourage the growth of reed beds which are allowed to flood and slow down river water. Another technique is known as floodplain zoning. Here, the areas closest to rivers are only used for low cost uses, such as playing fields and grazing. Higher cost land uses are kept away from the river on higher land. csl behring portal
