Which of the following is not a major greenhouse gas?
Which of the following is not a major greenhouse gas?
- A. Carbon dioxide
- B. Methane
- C. calcium carbonate
- D. water vapour
Step-by-step solution
Calcium carbonate (CaCO3) is a solid compound (e.g., limestone) and not a gas; it does not absorb and emit infrared radiation in the atmosphere, so it is not considered a greenhouse gas. In contrast, carbon dioxide, methane, and water vapor are well-known major greenhouse gases that trap heat in the Earth's atmosphere.
