Unit 7 Air pollution Quiz
.Particulate Mater
An atmospheric pollutant that is a small solid or liquid suspended in the air. It may cause lung irritation or disease in large enough quantities.
What is the largest suspected environmental problem associated with the burning of fossil fuels?
global warming
It is projected that an increase in carbon dioxide levels in the atmosphere will MOST LIKELY lead to
higher-than-average sea levels.
As the world population continues to rise, the demand for energy also continues to rise. Which of the following energy resources does not pollute Earth's atmosphere with carbon dioxide?
nuclear
Which layer of Earth's atmosphere contains the ozone layer, an important layer that helps protect life on Earth from UV radiation?
stratosphere
Which of these is MOST LIKELY to cause natural sulfur dioxide pollution?
volcanic activity
What human activity is most responsible for the damage to the ozone layer?
Burning of fossil fuels and the subsequent creation of acid rain.
Why is the increase in atmospheric carbon dioxide dangerous?
The gas inhibits the escape of heat from Earth's atmosphere, causing global warming.
Reducing the emissions of which gas will lead to reducing the greenhouse effect?
carbon dioxide
All of the following are sources of air pollution EXCEPT*
chlorofluorocarbons (CFCs).
Jill lives 2 miles from her workplace. Jill has decided that she wants to start conserving gasoline. Jill is concerned about the rising price of gas, as well as how the by-products from gas engines pollute the atmosphere. What solution would help Jill solve both problems most effectively?
Deciding to ride her bicycle to and from work, instead of driving.
Process by which atmospheric gases trap heat close to Earth's surface and prevent it from escaping into space. This is naturally occurring and necessary for life to exist.
Greenhouse Effect
What practice would probably NOT reduce the greenhouse effect?
Increased dependence on alternative energy sources, instead of gasoline.
This greenhouse gas is primarily emitted from the digestive processes of cattle. It is four times as powerful as a greenhouse gas than carbon dioxide.
Methane
Photochemical smog, lowered air quality, and increased greenhouse gas release is much more common in urban areas compared to rural areas. What explains the lowered air quality association with urban areas?
More fossil fuels are used for combustion in industry and cars, which are more concentrated in urban areas.
Layer in the Earth's atmosphere that shields life on Earth from harmful ultraviolet (UV) radiation.
Ozone Layer
What would happen if there was no greenhouse effect?
The Earth would be too cold to support life.
concentration of industrial factories
The map shows levels of air quality in parts of the United States and Canada. What is a contributing factor to the areas with unhealthy levels?
Chlorofluorocarbons (CFCs)
These chemicals are chemically unreactive under normal conditions, but over the Antarctic stratosphere, they break down and produce chlorine which breaks down ozone molecules.
Carbon Monoxide
This colorless, odorless, poisonous gas is produced by the combustion of carbon or organic fuels. When people cut the catalytic converters out of vehicles, more of this gas is released.
