It is a process of degradation of elements as a result of chemical, electro-chemical, or other reactions. Corrosion is when a refined metal, such as its oxide, hydroxide or sulphide state, is spontaneously converted to a more solid form, which contributes to material degradation. Too much humidity or condensation of water vapour on metal surfaces are the primary causes of corrosion. Metals with a greater reactivity series, such as iron and zinc, corrode quickly, whereas metals with a lower reactivity series, such as gold, platinum, and palladium, do not corrode. Corrosion is the breakdown of materials due to chemical reactions. Corrosion happens when a metal continues to oxidise.

When the stream comes down from the hills to plain areas with the eroded and transported materials, the absence of slope/gradient causes the river to lose it energy to further carry those transported materials. Corrosion also occurs when an acidic/basic corrosive substance touches another material. Rusting of iron and steel is perhaps the most common example of metallic corrosion. Corrosion is a process where the water or the moisture on the surface of the metal oxidizes with the atmospheric oxygen, it is an oxidation reaction. When iron comes into touch with air or water, rusting occurs, which is the most typical occurrence. General corrosion- It occurs as a result of rust.
