Q. Which of the following greenhouse gas is majorly released from the rice fields?

[A] Ozone

[B] Methane

[C] Nitrous oxide

[D] Ammonia

Answer: B


  • Growing rice produces methane, a greenhouse gas more than 30 times as potent as carbon dioxide.
  • Methane from rice fields contributes around 1.5 percent of total global greenhouse gas emissions and could grow substantially.
  • Flooded rice fields emit methane (CH4), which is second in importance to CO2 as a greenhouse gas.
  • A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect.
  • The primary greenhouse gases in the earth’s atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
