प्रश्न
Describe chemical weathering mentioning the processes involved in it.
उत्तर
Chemical weathering takes place with the help of agents as water, wind, and various organic acids, reacting in the chemical composition of rocks which are then disintegrated. Four main processes are the solution by dissolving salts in the rocks with water, carbonation works with the reaction of carbon dioxide with rocks, oxidation takes place through atmospheric oxygen reacting with minerals present in rocks, hydration is evident by mixing of rainwater with minerals in rocks, which expand by this and become heavy.
