UPSC NDA-1 – 2018
The correct answer is (B) hot and humid climate. Chemical weathering involves chemical reactions like hydrolysis, oxidation, carbonation, etc., which break down rocks. These reactions are significantly accelerated by higher temperatures and the presence of water. A hot climate increases the rate of chemical reactions, and a humid climate provides the necessary moisture (water) for these reactions to occur.
Chemical weathering is most effective in environments with high temperatures and abundant moisture, as these conditions promote the chemical breakdown of minerals in rocks.
