question
Explain why components that are naturally found in air can be considered air pollutants.
answer
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.
question
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?
answer
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..
question
Compare primary and secondary pollutants. Which is more harmful?
answer
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.
question
What is a possible long-term effect of continued exposure to air pollution?
answer
Some possible long-term effects of continued exposure to air pollution are emphysema, lung cancer, heart diseases, and eventual death.
