The correct Answer is:
To analyze the assertion and reason provided in the question, we can break it down step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that a higher concentration of CO2 in the atmosphere is causing global warming. - This is true because CO2 is a greenhouse gas that traps heat in the atmosphere. 2. **Understanding the Reason**: - The reason given is that this phenomenon is due to the greenhouse effect. - The greenhouse effect is a natural process where certain gases in the atmosphere, including CO2, trap heat from the sun, preventing it from escaping back into space. 3. **Linking Assertion and Reason**: - The assertion is correct as increased CO2 levels lead to more heat being trapped in the atmosphere, which contributes to global warming. - The reason is also correct because the mechanism through which CO2 causes global warming is indeed the greenhouse effect. 4. **Conclusion**: - Both the assertion and the reason are true statements. - Additionally, the reason provides a correct explanation for the assertion. Therefore, the assertion is true, the reason is true, and the reason is a correct explanation of the assertion. ### Final Answer: - Both the assertion and the reason are true, and the reason correctly explains the assertion. ---

Assertion: Higher concentration of CO_(2) in atmosphere is causing global warming. Reason: Excessive CO_(2) depletes ozone layer.

The reason for global warming is

Global warming is caused by ' greenhouse effect'. Justify.

Carbon dioxide is an essential component of atmosphere. However, when the concentration of CO_2 increases in the atmosphere, it can lead to global warming through green house effect. Similarly, rain water is an essential source of water. It has pH of 5.6 due to the formation of H^+ ions from the reaction of rain water with CO_2 present in the atmosphere. When pH of the rain water falls below 5.6 due to the presence of acids in the atmosphere, it has very damaging effects. Name three gases which are responsible for greenhouse effect.
