Expert Solution
Step 1
Chemical weathering occurs due to the variation of chemical composition of the rocks because of chemical reaction of the minerals present in the rocks. Main agents are oxidation, carbonation and hydrolysis. It mainly occurs in the surface of the Earth. Chemical weathering occurs in hot and humid climate.
