Question

Gases responsible for green house effect are

• A. ${\mathrm{CO}}_2$
• B. ${\mathrm{N}}_2\mathrm{O}$
• C. $\mathrm{CFC}$
• D. All of the above

Answer 1

The correct option is D

All of the above

The explanation for the correct answer:-

Option (D) All of the above:

1. The process in which Earth's surface is heated up to the troposphere is known as the Greenhouse Effect.
2. The higher concentration of gases like Carbon dioxide$\left({\mathrm{CO}}_2\right)$, Nitrous oxide$\left({\mathrm{N}}_2\mathrm{O}\right)$, and Chlorofluorocarbons$\left(\mathrm{CFCs}\right)$, are responsible for this heating up.
3. As the sun heats up Earth's surface with its sunlight, subsequently, the energy in the form of infrared radiation is reflected back to space.
4. These concentrated gases absorb this reflected energy in the greenhouse effect, which ultimately increases the global temperature.
5. Therefore from this point we can say that the greenhouse effect and global warming are related to each other.

Therefore, gases responsible for the greenhouse effect are option (D) All of the above.
