APES Acid Deposition Quiz

What are the primary sources of acid deposition?

• Acid deposition is caused by excessive use of pesticides and fertilizers.

• Acid deposition is a natural process caused by volcanic eruptions.

• The sources of acid deposition include industrial emissions, vehicle exhaust, and burning of fossil fuels.

• Acid deposition is primarily caused by deforestation and land clearing.

How does acid deposition affect soil?

• Acid deposition can increase soil pH and enhance nutrient availability.

• Acid deposition only affects the surface of the soil.

• It can raise the soil pH and render soil useless

• Acid deposition can lower soil pH, leach nutrients, and release toxic metals.

What are the effects of acid deposition on water?

• Acid deposition has no effect on water.

• The effects of acid deposition on water include increased pH levels, reduced toxicity, and improved water clarity.

• The effects of acid deposition on water include increased oxygen levels, improved water quality, and enhanced biodiversity.

• The effects of acid deposition on water include acidification, harm to aquatic life, and disruption of pH balance.

How does acid deposition impact forests?

• Acid deposition has no impact on forests.

• Acid deposition can damage trees and plants, making them more vulnerable to diseases and pests.

• Acid deposition helps trees and plants grow stronger.

• Acid deposition only affects the soil, not the trees and plants.

Scientists are testing the effect of different scrubber technologies on the removal of pollutants from coal power plants. The scrubbers use a slurry of limestone and water.

Which of the following best describes the impact of modifying the slurry by increasing the amount of limestone?

• The amount of sulfur dioxide released will decrease.

• The amount of ground-level ozone released will decrease

• The amount of water released will increase.

• The amount of carbon monoxide released will increase.

Scientists want to examine the effects of a coal-burning power plant on the pH of a lake that is downwind of the power plant. They take samples from a lake that is not downwind of the power plant to serve as a control. However, they did not realize that the lake they chose as a control group was a geothermal hot spring with acidic water.

• Using this control would not have an effect on the outcome because the high temperature of the hot spring reduces the acidity of the water in the lake.

• The coal-burning power plant would appear to have a much larger effect on the pH of the experimental group because the

  pH in the control lake would be elevated from the acidic water.

• The coal-burning power plant would not appear to have a large impact because the pH levels of the two lakes would be similar.

• The coal-burning power plant would affect both lakes because the Coriolis effect and weather patterns would circulate pollutants in the atmosphere.

Which of the following best describes the efficiency of dry scrubbers at removing particles that are less than 2 micrometers in diameter?

• Dry scrubbers are less than 20% efficient at removing particles less than 1μm and increase to over 50% efficiency at removing particles between 1 and 2μm

  .

• Dry scrubbers are between 50% and 90% efficient at removing particles less than 2μm, depending on the flow rate.

• Dry scrubbers are between 5% and 40% efficient at removing particles less than 2μm in size.

• Dry scrubbers are less than 10% efficient at removing particles less than 1μm in size.
