These reactions can alter a rock and transform the rock into sand, clays, and other minerals. Like mechanical weathering, there are several different types of chemical weathering. One type is oxidation, the reaction of oxygen with …
WebIn chemical weathering, the rock disintegrates or even dissolves because a chemical reaction changed the composition of the rock. Rusting is an example. If iron in rock comes in contact with oxygen in the atmosphere, a chemical reaction called rusting occurs. WebWeathering causes the disintegration of rock near the surface of the earth. Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice.
