Question 1

1.

Which of the following best describes one way the Clean Air Act helped reduce air pollution?

Proposed incentives for countries to reduce carbon emissions

Implemented a program to manage hazardous and nonhazardous wastes

Created a fund to aid developing countries in reducing ozone-depleting emissions

Introduced regulatory measures to control the amount of lead in fuels

Question 2

2.

Which of the following energy sources produces the most air pollutants when used during the generation of electricity?

Fuel oil

Photovoltaic cells

Uranium

Natural gas

Question 3

3.

Industrial scrubbers and electrostatic precipitators collect enormous amounts of particulate matter (coal ash) at coal-burning power plants. Which of the following best describes an environmental disadvantage of using industrial scrubbers and electrostatic precipitators for pollution abatement?

Industrial scrubbers and electrostatic precipitators cannot remove fine particles like dust and smoke from the waste, so a secondary measure must be used.

Coal ash contains toxic levels of several different pollutants, so when it is collected and stored long-term in coal ash ponds, there is increased risk of exposure to toxic metals.

Industrial scrubbers and electrostatic precipitators are very costly to install and increase the cost of operating coal-burning power plants, leading to increased costs for consumers.

Coal ash is highly flammable, and it is very hazardous to ship the materials to hazardous waste landfills.

Question 4

4.

Which of the following environmental problems is most often linked to the combustion of fossil fuels?

Thermal inversions in mountainous coastal areas

Cultural eutrophication in surface waters

Photochemical smog formation in the troposphere

Ozone thinning in the stratosphere

Question 5

5.

Which of the following best describes a natural process that adds carbon dioxide to the atmosphere?

Carbon dioxide is released from the interior of Earth during volcanic eruptions.

Plants excrete carbon dioxide during photosynthesis.

Deposition of sediments into ocean basins release carbon dioxide from rock.

Burial of dead plants and animals in swamps and bogs allows carbon dioxide to escape to the atmosphere.

Question 6

6.

Which of the following best describes a potential unintended negative consequence of implementing measures to control acid deposition?

A reduction in sulfur for crops as a result of less acidic rainfall, leading to an increased need for sulfur supplements

A reduction in acid mine drainage, resulting from a reduced need for nuclear fuel and uranium mining

A reduction in environmental lead, leading to decreased negative health effects in humans and wildlife

A reduction in mortality rates in freshwater aquatic organisms from an increase in pH of the water

Question 7

7.

Which of the following contributes to global climate change through the direct release of carbon dioxide into the atmosphere?

Growing fast-growing crops in open fields

Use of foams and packing materials that contain chlorofluorocarbons

Generating electricity at a nuclear power plant

Transporting products from one continent to another on a cargo ship

Question 8

8.

A community located downwind from a coal-fired power plant has seen a recent increase in the number of dead and dying trees. A soil scientist measured values for the following parameters before and after the trees died off. Which of the following soil data should be used to determine if the coal-fired power plant emissions were the cause of the damage to the trees?

Pesticide and herbicide residue levels

Parent material composition

Calcium and aluminum levels

Moisture content and water retention
