Correct Answer - Option 2 : Water vapour

The correct answer is Water vapor.

 

  • A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect.
  • The primary greenhouse gases in Earth's atmosphere are
    • Water vapor (H2O)
    • Carbon dioxide (CO2)
    • Methane (CH4)
    • Nitrous oxide (N2O), and ozone (O3).
  • Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C, rather than the present average of 15 °C.\

 

  • Water vapor accounts for the largest percentage of the greenhouse effect, between 36% and 66% for clear sky conditions and between 66% and 85% when including clouds.
  • Water vapor absorbs electromagnetic radiation in various bands in the infra-red region.
