GEOLOGY

Detailed explanation-1: -Chemical weathering involves the interaction of rock with mineral solutions (chemicals) to change the composition of rocks. In this process, water interacts with minerals to create various chemical reactions and transform the rocks.

Detailed explanation-2: -There are five types of chemical weathering: carbonation, hydrolysis, oxidation, acidification, and lichens (living organisms).

Detailed explanation-3: -Chemical weathering occurs when water dissolves minerals in rocks, resulting in new compounds. This is also known as hydrolysis. An example would be when water comes in the proximity of granite. Feldspar crystals present inside the rock react chemically, forming clay minerals.

Detailed explanation-4: -The weathering of rocks occurs through both physical and chemical processes. Physical weathering is the breakdown of rock into smaller pieces without altering the chemical composition of the rock.
