Which gases are significant contributors to the greenhouse effect?

Which gases are significant contributors to the greenhouse effect?

• A. Oxygen, hydrogen, carbon monoxide
• B. Nitrogen, ozone, argon
• C. Carbon dioxide, methane, nitrous oxide, water vapor
• D. Helium, neon, chlorine

Answer: (C)

The significant contributors to the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor, making the choice of these gases as the correct answer. Each of these gases plays a critical role in trapping heat in the Earth's atmosphere, which contributes to the overall warming of the planet. Carbon dioxide is produced through various human activities, such as the burning of fossil fuels, deforestation, and certain industrial processes. It is one of the most significant greenhouse gases due to its long atmospheric lifetime and ability to absorb infrared radiation. Methane is another potent greenhouse gas that is released during the production and transport of coal, oil, and natural gas. Additionally, agricultural practices, especially livestock production and rice cultivation, contribute to methane emissions. Although it exists in smaller quantities compared to carbon dioxide, methane is far more effective at trapping heat in the atmosphere over a shorter time frame. Nitrous oxide, primarily emitted from agricultural and industrial activities, as well as during combustion of fossil fuels and solid waste, is also a potent greenhouse gas. It has a much greater heat-trapping ability than carbon dioxide. Water vapor, while it is a natural greenhouse gas present in significant amounts in the atmosphere, is primarily influenced by temperature rather than directly emitted from human activities. As
