nitrogen oxides and sulfur oxides

Which of the following is not a source of outdoor air pollution? car emissions factory emissions radon gas volcanic eruptions

radon gas

What effect does burning fossil fuels during manufacturing and energy production have on outdoor air pollution?

Burning fossil fuels during manufacturing and energy production has a huge effect on outdoor air pollution because it produces harmful gases such as ozone that can be a large contributor in to heating up the earth. This can also lead to gases that cause acid rain, smog and other serious types of pollution.

How does burning fossil fuels affect indoor air pollution?

Burning fossil fuels indoors such as coal, and oil, will possibly create carbon monoxide pollution, which can lead to many respiratory diseases.

Explain the process of acid rain

First, sulfur oxides and nitrogen oxides are given off by factories and vehicles as products of burning fossil fuels. These gases rise into the atmosphere. Then, these oxides combine with the water in the clouds to form sulfuric and nitric acids. Last, the acid precipitation falls to Earth as precipitation, such as snow or rain.

Which statement is true about ozone? Ozone helps human health no matter where it occurs. Ozone is a harmful pollutant no matter where it occurs. Ozone high in the atmosphere is a pollutant, but near Earth's surface, it provides protection from harmful rays. Ozone high in the atmosphere protects Earth's surface from harmful rays, but near Earth's surface, it is a pollutant.

Ozone high in the atmosphere protects Earth's surface from harmful rays, but near Earth's surface, it is a pollutant.

Why is the use of fertilizers on lawns in residential areas an example of nonpoint pollution?

Residential areas, includes a lot of people and a lot of homes so there wont be a specific point of where the pollution is coming from.

What is the difference between the "helpful" and "harmful" ozone?

The helpful ozone can be found in the upper atmosphere, and this is the ozone that shields humans from harmful UV radiation. Harmful ozone can be found in the lower atmosphere and this ozone is a pollutant and not safe for humans.

What evidence supports the claim that walking and biking to work would have a positive effect on air pollution?

Walking and biking don't produce any emissions like vehicles do, so if more people would walk and bike to work, the pollution would definitly reduce.

Indoor pollutants include pet hair and dust, which are _____, and radon and carbon monoxide, which are ).

allergens gases

What are two nonpoint pollution sources that might bother a person with respiratory issues?

cars on the highway and nearby factories
