You are to examine these two statements carefully and select the answe...
Statement I: Chemical weathering processes are found more active in hot and humid environment.
Statement II: High temperature and rainfall help in the process of decomposition of rocks.
Explanation:
Both Statement I and Statement II are individually true. However, Statement II is the correct explanation of Statement I.
Chemical Weathering and Hot and Humid Environment:
- Chemical weathering refers to the breakdown and alteration of rocks through chemical reactions.
- In hot and humid environments, there is an abundance of moisture and heat, which accelerates chemical reactions.
- The presence of water and high temperatures provide favorable conditions for the chemical reactions to occur more rapidly.
- Water acts as a solvent, allowing minerals in the rocks to dissolve and undergo chemical changes.
- The heat increases the kinetic energy of molecules, making them more reactive and increasing the rate of chemical reactions.
- Therefore, chemical weathering processes are found to be more active in hot and humid environments.
Decomposition of Rocks and High Temperature/Rainfall:
- Decomposition of rocks involves the breakdown of rocks into smaller particles or minerals.
- High temperature and rainfall play a significant role in the process of rock decomposition.
- High temperatures increase the rate of chemical reactions, leading to the breakdown of rocks.
- Rainfall provides the necessary moisture for chemical reactions to occur.
- Water seeps into the cracks and pores of rocks, facilitating chemical weathering and decomposition.
- The dissolved minerals in the water can react with the minerals in the rocks, causing them to decompose.
- Both high temperature and rainfall contribute to the process of rock decomposition.
Explanation of the Relationship:
- Statement II provides a clear explanation for Statement I.
- The high temperature and rainfall mentioned in Statement II are the factors responsible for the chemical weathering processes mentioned in Statement I.
- The combination of high temperature and rainfall in a hot and humid environment creates the ideal conditions for chemical weathering and rock decomposition.
- Therefore, both statements are individually true, and Statement II serves as the correct explanation for Statement I.
Conclusion:
- Both statements are true, and Statement II provides the correct explanation for Statement I.
- Therefore, the correct answer is option 'A': Both the statements are individually true, and Statement II is the correct explanation of Statement I.

Chemical weathering pertains to the changes in rock structure under the action or influence of chemical reactions. It is most active in warm and humid conditions. When rain falls, the water is slightly acidic because carbon dioxide from the air dissolves in it. Minerals in rocks may react with the rainwater, causing the rock to be weathered.
