- Major greenhouse gases include Carbon Dioxide (CO2), Methane (CH4), Nitrous Oxide (N2O), Fluorinated Gases, and Water Vapour (H2O). - Water vapour is the most abundant greenhouse gas and contributes significantly to the natural greenhouse effect. - Nitrogen (N2) and Oxygen (O2), the main components of the atmosphere, do not absorb infrared radiation effectively.
Select the correct option from the codes given below about greenhouse gases from the following: i. Methane ii. Nitrogen iii. Nitrous oxide iv. Water vapours Code :
