Atmospheric Pollution Practice 100%

What are some possible sources of air pollution?

Air pollution occur naturally or as a result of human activity. Volcanoes are an example of a natural cause of air pollution. Combustion of fuels for power generation, industrial activity, and exhaust from motor vehicles are all additional sources of air pollution.

Explain why components that are naturally found in air can be considered air pollutants.

Components of air, like carbon dioxide, can be considered pollutants when human activity causes their concentration to be larger than normal. At higher concentrations, naturally occurring gases can have undesirable consequences on the environment. High levels of carbon dioxide can cause an increase in Earth's temperature.

What is a possible long-term effect of continued exposure to air pollution?

Continued exposure to air pollution could cause people to develop respiratory or cardiovascular illness. It is possible for individuals to develop cancer as a result of prolonged exposure to air pollution as well.

Compare primary and secondary pollutants. Which is more harmful?

Primary pollutants are pollutants that are directly emitted from a pollution source. Secondary pollutants are created as a result of interaction in the atmosphere of primary pollutants. Primary pollutants can be as harmful as secondary pollutants.

Soot results from burning organic compounds. Soot is an example of _______. a. a primary pollutant b. a secondary pollutant c. a tertiary pollutant d. none of the above

A. A Primary pollutant

The ozone layer is located in the _______. a. troposphere b. stratosphere c. mesosphere d. thermosphere

B. Stratosphere

Which two layers of the atmosphere are responsible for the majority of solar radiation absorption? a. stratosphere and troposphere b. stratosphere and thermosphere c. troposphere and thermosphere d. troposphere and mesosphere

B. Stratosphere and thermosphere

Which of the following groups of people would be the least affected by air pollution? a. people with asthma b. infants c. teenagers d. the elderly

C. Teenagers

How are the troposphere, stratosphere, and thermosphere important for supporting life on Earth? Which layer of the atmosphere is likely the most important for life on Earth?

The troposphere contains 75% of the atmospheric mass as well as the oxygen and carbon dioxide plants and animals need to survive. The stratosphere's ozone layer absorbs ultraviolet radiation which is harmful to living organisms. The thermosphere absorbs solar radiation and helps to regulate the Earth's temperature. All layers of the atmosphere are important for supporting life on the Earth, but the troposphere is the most important as it provides organisms with the air they breathe.

Carbon monoxide is a common atmospheric pollutant.
