Greenhouse gas is a)Nitrogen b)Oxygen c)Methene d)Carbon dioxide. The correct answer is option 'D'. Can you explain this answer? ?

Question

Answer

My answer to your question is: Carbon dioxide is called a greenhouse gas because it is one of the gases in the atmosphere that warms the Earth through a phenomenon called the greenhouse effect. Pls Upvote my answer.

Answer

Greenhouse gas is mainly carbon dioxide and methene also so right answer is option c and d.

Thank you

Answer

Greenhouse gas refers to a gas that traps heat in the Earth's atmosphere and contributes to the greenhouse effect. These gases allow sunlight to enter the atmosphere, but prevent some of the heat from escaping back into space. This process leads to the overall warming of the Earth's surface and is considered a major factor in climate change.

The correct answer to the question is option 'D' - Carbon dioxide. Carbon dioxide is one of the most important greenhouse gases and plays a significant role in global warming. Here is an explanation of why carbon dioxide is a greenhouse gas and its impact on the environment:

1. Carbon Dioxide (CO2)
- Carbon dioxide is a naturally occurring gas in the Earth's atmosphere, but human activities such as burning fossil fuels (coal, oil, and natural gas), deforestation, and industrial processes have significantly increased its concentration.
- CO2 absorbs and re-emits infrared radiation, trapping heat in the atmosphere and causing the greenhouse effect. This effect is essential for maintaining the Earth's temperature within a habitable range.
- However, the excessive release of CO2 from human activities has led to an imbalance in the natural carbon cycle, resulting in an increase in atmospheric CO2 levels. This has caused a rise in global temperatures, leading to climate change.

2. Other Greenhouse Gases
While carbon dioxide is the most well-known greenhouse gas, there are several other gases that also contribute to the greenhouse effect. Some of these gases include:

- Methane (CH4): Methane is produced through natural processes (e.g., decomposition of organic matter) and human activities (e.g., livestock farming, rice cultivation, and fossil fuel extraction). It is a potent greenhouse gas, trapping heat more effectively than carbon dioxide, but its concentration in the atmosphere is much lower.
- Nitrous Oxide (N2O): Nitrous oxide is mainly emitted from agricultural and industrial activities, as well as combustion processes. It has a high global warming potential and can remain in the atmosphere for a long time.
- Ozone (O3): Ozone is present in the Earth's atmosphere in two forms: the protective ozone layer in the stratosphere and ground-level ozone. Ground-level ozone is a greenhouse gas and a pollutant that is formed through chemical reactions involving other pollutants and sunlight.
- Water Vapor (H2O): Water vapor is the most abundant greenhouse gas, but its concentration is highly variable and depends on temperature and weather conditions. While it plays a crucial role in the Earth's climate system, it is considered a feedback rather than a driver of climate change.

Conclusion
Carbon dioxide (CO2) is the correct answer as it is one of the most significant greenhouse gases contributing to global warming and climate change. However, it is important to note that other greenhouse gases such as methane, nitrous oxide, ozone, and water vapor also play a role in the greenhouse effect and should be considered when addressing climate change issues.

Answer

D is right

Answer

Answer

Carbon dioxide is green house gas so the answer is d

Answer

A molecule of carbon dioxide (CO2) is made up of one carbon atom and two oxygen atoms. Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. Without it, our planet would be inhospitably cold. ... It has a concentration of about 400 ppmv (parts per million by volume) in Earth's atmosphere.
