Detailed explanation-1: -Carbon dioxide, methane and water vapour are greenhouse gases. But the main constituents of the atmosphere nitrogen and oxygen are not greenhouse gases.

Detailed explanation-2: -Carbon monoxide is not a greenhouse gas. Methane, carbon dioxide, nitrogen dioxide, ozone and water vapour gases are the greenhouse gases.

Detailed explanation-3: -The vibrations of any gas molecule such as nitrogen and oxygen tend to be invisible to the electromagnetic field. It does not absorb infrared light, in other words, they are not infrared active. Hence, both these gases are not greenhouse gases as they are transparent to infrared light.

Detailed explanation-4: -Oxygen and nitrogen are not greenhouse gases, because they are transparent to infrared light. These molecules are invisible because when you stretch one, it doesn’t change the electric field. These are symmetric molecules, made of two identical atoms whose electric fields just cancel each other out.

Detailed explanation-5: -Greenhouse gases that occur both naturally and from human activities include water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone (O3).
