Greenhouse Gases (GHGs) are the gases that lead to the warming of the Earth. Even though these are naturally present in the Earth's atmosphere, their quantity is increasing exponentially due to the burning of Fossil Fuels, Crop/Biomass Residue, etc.
The following are examples of GHGs-
- Carbon Monoxide- Carbon monoxide (CO) is a colorless, odorless, and tasteless gas.- It is formed as a result of incomplete combustion of carbon-containing materials.
- Methane- Methane (CH₄) is a potent greenhouse gas that contributes to global warming.- Methane is produced by the anaerobic decomposition of organic matter.
- Carbon Dioxide: Carbon dioxide (CO₂) is a colorless, odorless, and tasteless gas.- It is formed as a natural outcome of combustion of carbon-containing materials.
- Hydrofluorocarbons: Potent greenhouse gases (GHG) that have global warming potentials that range from hundreds to thousands of times that of carbon dioxide.
- Nitrous oxide molecules stay in the atmosphere for an average of 121 years before being removed by a sink or destroyed through chemical reactions.
Hence option (a) is the correct answer.
