A) It helps reduce the amount of a greenhouse gas in the atmosphere.
B) It helps increase the amount of oxygen in the atmosphere.
C) It helps reduce carbon dioxide emissions.
D) It helps in the formation of clouds.

Answer 1

C) It helps reduce carbon dioxide emissions

Explanation:

• Methane being a vital greenhouse gas and produces 84 times more heat than carbon dioxide, its concentration varies across the seasons and can remain in the atmosphere for a period of 12 years.

• Methane has the ability to stay in the atmosphere without the oxygen for a longer duration.

• The gas can produce water vapor through the chemical reaction when it reaches the mesosphere and is most likely to produce clouds.

• The environmental benefits of this gas is that it can produce energy by mass and are more refined than oil and creates less pollution and pollutants.
