Question

If the Carbon dioxide in the atmosphere increases, why will the amount of heat radiated out of the Earth decrease?

• A. Because carbon dioxide easily allows heat to escape from the atmosphere.
• B. Because carbon dioxide in the atmosphere traps the heat and prevents it from going out.
• C. Because carbon dioxide will refract the heat.
• D. Because carbon dioxide will form other gases in the presence of heat.

Answer 1

The correct option is B Because carbon dioxide in the atmosphere traps the heat and prevents it from going out.

Gases in the atmosphere, such as carbon dioxide, trap heat just like the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases.
