Practice AP Environmental Science Unit 7 questions on air pollutants, photochemical smog, indoor air, pollution controls, and acid deposition.
Respond to parts A, B, C, D, E, F, and G.
One major environmental problem is air pollution. Air pollution can come from natural or
anthropogenic sources. Motor vehicles can be a source of particulate matter (PM) and other
pollutants.
Identify an anthropogenic source of particulate matter, other than from motor vehicles.
One way to reduce pollutants associated with motor vehicles is to use a vapor recovery
nozzle. Describe one way a vapor recovery nozzle is used to reduce atmospheric pollution.
Acid rain is another air pollutant linked to motor vehicles. Over the past few years, there
has been an increase in the number of people working from home, so fewer people are
commuting to work in their personal vehicles.
Explain how a decrease in the number of people commuting to work in their personal
vehicles could lead to a reduction in acid rain.
The diagram shows the movement of one adult manatee over a 12 -hour period across an active shipping channel during the winter. Manatees are large, aquatic, herbivorous mammals that primarily eat seagrass. Manatees can travel several miles to graze. Manatees mature slowly, have low biotic potential, and inhabit warm coastal waters. They cannot survive in water below 20°C for extended periods of time.

Describe how summertime weather conditions can increase the frequency of photochemical smog.
Identify one ecological problem that results from exposure to photochemical smog.
A potential solution to reduce photochemical smog in urban areas with high automobile traffic is to replace gasoline-powered cars with cars powered by hydrogen fuel cells.
What important phenomenon that often plays a role in air pollution episodes is illustrated in the diagram above?
Albedo
Greenhouse effect
Inversion
Stratification
Heat-island effect
A student enters a science fair competition with a project on demonstrating how and particulates come from a variety of natural sources. Which of the following would her experiment most likely conclude?
comes from decomposition and respiration and particulates from pollen and dust.
Volcanic eruptions do not produce or particulates.
is produced from nuclear energy power plants.
Particulate matter is completely anthropogenic.
