Question

Name the major greenhouse gases of the atmosphere with their contributions.

Answer 1

1. Greenhouse gases (GHGs) trap the infrared radiations (IR) coming from the Sun.
2. They re-radiate it back to Earth’s atmosphere.
3. Due to this, they are responsible for increasing the temperature of the atmosphere.

Major greenhouse gases are:

1. Carbon dioxide (CO₂)
2. Water Vapour
3. Methane (CH₄)
4. Ozone (O₃)
5. Nitrous oxide (NO)
6. Chlorofluorocarbons (CFC)

Due to human intervention, the amount of greenhouse gases in the atmosphere has increased remarkably causing global warming.
