Which of the following is not a greenhouse gas?

Correct option is C

 
Helium is not a greenhouse gas. Unlike gases such as carbon dioxide, methane, and water vapor, helium does not trap heat in the Earth’s atmosphere. It is an inert gas and has no effect on the greenhouse effect, which is crucial to regulating Earth’s temperature.
Important Key Points:
1. Helium is a noble gas with minimal reactivity.
2. It is used in applications like medical imaging and scientific research.
3. Greenhouse gases trap heat and contribute to global warming.
4. Major greenhouse gases include carbon dioxide, methane, and water vapor.
5. Greenhouse gases are essential in maintaining Earth’s temperature but can lead to climate change when excessive.
6. Helium’s lack of chemical reactivity prevents it from contributing to the greenhouse effect.
Knowledge Booster:
· Water vapor is a natural greenhouse gas but is not directly regulated.
· Methane is a potent greenhouse gas, commonly emitted by agriculture and waste.
· Carbon dioxide is the primary greenhouse gas responsible for human-induced climate change.
