How Is The Problem Of Floods Made Worse By Soil Erosion

A continuous process of removing the top soil layer by water, rain or wind is known as soil erosion. Soil, in the form of mud, rock and tiny particles, is replaced by ocean currents as well. Erosion is actually a natural process, but intervention of humans has made it a major problem. Normally, soil erosion is useful for our ecosystem, but excess of it creates disadvantages.Because of removal of vegetation and deforestation, the ecosystem gets damaged and there is an imbalance.
