A. Laughing gas
B. Tear gas
C. Marsh gas
D. non-greenhouse gas
Answer: C. Marsh gas
Methane is known as Marsh gas.
Detailed Solution:
- Methane (CHâ‚„) is a colorless, odorless gas that is the main component of natural gas. It is produced primarily through biological processes in environments with low oxygen, such as wetlands and marshes, which is why it’s referred to as marsh gas.
- It is created by anaerobic decomposition of organic matter by bacteria in waterlogged conditions like marshes, swamps, and wetlands.
- Methane is also a greenhouse gas that contributes to global warming, as it traps heat in the atmosphere.
Why the other options are incorrect:
- A. Laughing gas: This refers to nitrous oxide (Nâ‚‚O), not methane.
- B. Tear gas: This is a chemical compound (such as CS gas) used in riot control, not related to methane.
- D. Non-greenhouse gas: Methane is a potent greenhouse gas, so this option is incorrect.
Hence, Methane is commonly called Marsh gas.
