Which one of the following greenhouse gases is in largest concentration in the atmosphere?

Options

  1. AChlorofluorocarbon
  2. BNitrous oxide
  3. CCarbon dioxide
  4. DMethane

Correct answer

C. Carbon dioxide

Step-by-step solution

Greenhouse gases are those that absorb and emit infrared radiation in the wavelength range emitted by Earth. In order, the most abundant greenhouse gases in Earth's atmosphere are: Water vapor ( H ₂ O ) , Carbon dioxide ( CO ₂ ) , Methane ( CH ₄ ) , Nitrous oxide ( N ₂ O ) , Ozone ( O ₃ ) , Chlorofluorocarbons (CFCs), Hydro fluorocarbons (incl. HCFCs and HFCs)
