Question

Which of the following may be the cause of greenhouse effect?

• A. Burning of fossil fuel like coal in the industries for producing electricity.
• B. Burning of fossil fuel leads to high emissions of carbon di-oxide gas.
• C. Nitrous oxide, also a green house gas is produced during nylon and nitric acid production.
• D. All of the above

Answer 1

The correct option is D All of the above

A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect on planets. The primary greenhouse gases in Earth's atmosphere are water vapour $\left(H_{2}O\right)$, carbon dioxide $\left(C{O}_2\right)$, methane $C{H}_4)$, nitrous oxide $\left(N_{2}O\right)$ and ozone $\left(O_3\right)$.

Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and other biological materials, and also as a result of certain chemical reactions. Nitrous oxide is emitted during nylon and nytric acid production, agricultural and industrial activities, combustion of fossil fuels and solid waste, as well as during treatment of wastewater.
