Question : Which gas is primarily responsible for global warming?
Option 1: Carbon monoxide
Option 2: Nitrogen dioxide
Option 3: Methane
Option 4: Ozone
Correct Answer: Methane
Solution : The correct answer is (c) Methane
While carbon dioxide (CO2) is the most prevalent greenhouse gas emitted by human activities, methane (CH 4) is considered more potent in terms of its heat-trapping ability. Methane is released through various sources, including natural processes like wetlands and the decay of organic matter, as well as human activities such as agriculture, livestock production, and the extraction and use of fossil fuels. Although methane concentrations in the atmosphere are lower than carbon dioxide, its warming potential is significantly higher, making it a major contributor to global warming and climate change.
