Question

Which gas is the primary contributor to the Greenhouse effect?

• A. \(CO_2\)
• B. \(O_2\)
• C. \(N_2\)
• D. \(CH_4\)

Hint:

Remember: CO2 is the most significant gas contributing to the greenhouse effect, but other gases also play a role.

Answer 1

The Correct Option is A

Step 1: Understanding the Greenhouse effect.
The greenhouse effect refers to the process where certain gases in Earth's atmosphere trap heat, contributing to global warming. Step 2: Main contributors.
The primary gas responsible for the greenhouse effect is Carbon Dioxide (\(CO_2\)), along with other gases like methane (\(CH_4\)) and water vapor. However, CO2 is considered the most significant due to its high concentration and long-term effects. Step 3: Conclusion.
Hence, the correct answer is \(CO_2\) as the main contributor to the Greenhouse effect.
