Natural disasters, such as volcanic eruptions and wildfires, can release pollutants into the air, but they are not considered major sources of air pollution because they are not human-caused.

Sulfur dioxide is a major component of acid rain, which is formed when sulfur dioxide and nitrogen oxides react with water vapor in the atmosphere.

Exposure to ozone can cause a variety of respiratory problems, including asthma, bronchitis, and emphysema.

Increasing the use of fossil fuels will increase air pollution, as fossil fuels are a major source of pollutants.

Air purification is the process of removing pollutants from the air, typically using a filter or other device.

Tobacco smoke, cleaning products, and pesticides are all major sources of indoor air pollution.

Smog is caused by a combination of sunlight and air pollution, particularly nitrogen oxides and volatile organic compounds.

Nitrogen is not a greenhouse gas, as it does not trap heat in the atmosphere.

Air pollution control, prevention, and mitigation are all terms used to describe the process of reducing the amount of pollutants released into the air.

Solar panels are not air pollution control devices, as they do not remove pollutants from the air.

Human activities, particularly the burning of fossil fuels, are the primary cause of climate change.

Air pollution can cause a variety of health problems, including heart disease, cancer, and stroke, but it does not improve lung function.

The troposphere is the layer of the atmosphere that is closest to the Earth's surface and contains most of the air that we breathe.

Oxygen is not an air pollutant, as it is a natural component of the atmosphere.

Solar power is the process of converting sunlight into electricity using photovoltaic cells.
