The major sources responsible for the presence of NO, N2O, NO2 in the atmosphere is / are:
Correct answer: C. Fossil fuel combustion
- A. Fertilizers
- B. Biological decay of organic matter
- C. Fossil fuel combustion
- D. All of these
Explanation
Fossil fuel combustion is the major source of NO, NO2, and N2O in the atmosphere. This process occurs in vehicles, industrial facilities, and power plants, where high temperatures lead to the formation of nitrogen oxides. Fertilizers and biological decay are lesser sources and primarily contribute to other types of nitrogen emissions, such as ammonia and organic nitrogen compounds, rather than directly to nitrogen oxides.
