The correct answer is: C. Photochemical oxidation of organic number
A. Volcanic eruptions and lightening discharge are natural sources of air pollution. Volcanic eruptions release ash, sulfur dioxide, and other gases into the atmosphere. Lightening discharges can produce ozone, which is a major component of smog.
B. Biological decay of vegetable matter is not a natural source of air pollution. This process releases methane, which is a greenhouse gas, but it does not produce air pollutants.
D.
None of the above is not a correct answer because it does not specify which of the options is not a natural source of air pollution.Air pollution is the contamination of the air by noxious gases, dust, or other particulate matter. It can be caused by natural sources, such as volcanic eruptions and forest fires, or by human activities, such as burning fossil fuels and industrial emissions. Air pollution can have a significant impact on human health, causing respiratory problems, heart disease, and cancer. It can also damage plants and animals, and contribute to climate change.
There are a number of things that can be done to reduce air pollution, including:
- Reducing emissions from vehicles and power plants
- Using cleaner energy sources, such as solar and wind power
- Planting trees and other vegetation
- Improving air quality standards
Air pollution is a serious problem, but it is one that can be solved. By taking action to reduce emissions and improve air quality, we can protect our health and the environment.
