Answer: Option C
Solution
Answer: Option C
Solution:
Underground water predominantly acts as the agent of chemical erosion of soil. Chemical weathering changes the molecular structure of rocks and soil. The important characteristics of surface conditions that lead to chemical weathering are the presence of water (in the air and on the ground surface), the abundance of oxygen, and the presence of carbon dioxide, which produces weak carbonic acid when combined with water.
