GENERAL GEOLOGY

Detailed explanation-1: -This is the decomposition of rocks due to chemical reactions occurring between the minerals in rocks and the environment. The examples below illustrate chemical weathering. Water, and many chemical compounds found in water, is the main agent of chemical weathering.

Detailed explanation-2: -Chemical weathering is the weakening and subsequent disintegration of rock by chemical reactions. These reactions include oxidation, hydrolysis, and carbonation. These processes either form or destroy minerals, thus altering the nature of the rock’s mineral composition.

Detailed explanation-3: -There are five types of chemical weathering: carbonation, hydrolysis, oxidation, acidification, and lichens (living organisms).

Detailed explanation-4: -There are different types of chemical weathering processes, such as solution, hydration, hydrolysis, carbonation, oxidation, reduction, and chelation. Some of these reactions occur more easily when the water is slightly acidic.
