sri prakash [email protected] Q1. Which of the following industrial processes is a major source of sulfur dioxide (SO2) emissions? $Select the correct option: A. Aluminum smelting B. Leather tanning C. Burning of natural gas D. Coal combustion in power plants Correct Answer: D. Coal combustion in power plants Explanation: Coal combustion in power plants is a major source of sulfur dioxide (SO2) emissions. SO2 is a significant contributor to air pollution and acid rain. While other listed processes also contribute to environmental pollution, coal combustion specifically is known for releasing large amounts of SO2 due to the sulfur content of coal. Q2. Consider the following statements about the environmental impact of fossil fuel combustion: 1. Combustion of fossil fuels is a major source of carbon dioxide, a greenhouse gas that contributes to global warming. 2. Sulfur dioxide and nitrogen oxides, produced from burning fossil fuels, can lead to acid rain, which harms ecosystems and structures. 3. The process of extracting and transporting fossil fuels does not contribute to environmental degradation. 4. Renewable energy sources such as wind and solar power emit more greenhouse gases during production than fossil fuels. $Which of the statements given above are correct? A. 1 only B. 1 and 2 only C. 3 and 4 only D. None of the above Correct Answer: B. 1 and 2 only Explanation: Statements 1 and 2 are correct as they accurately describe the environmental impacts of fossil fuel combustion, including the emission of greenhouse gases and the formation of acid rain. Statement 3 is incorrect because the extraction and transportation of fossil fuels can cause significant environmental degradation, including habitat destruction and oil spills. Statement 4 is incorrect; renewable energy sources generally emit far fewer greenhouse gases than fossil fuels over their lifecycle. superkalam.com Discover your learning potential with SuperKalam
