1. Acid Rain Quiz

2. What is acid precipitation?
Any precipitation with a pH of 5.6
Precipitation with a pH of less that 5.6
Precipitation that is not neutral
Precipitation with a high pH

3. Which is a direct effect of acid rain on vegetation?
Acid leaches nutrients from the soil, making plants grow poorly
Acid damages the foliage of plants
Acid makes the plants grow faster

4. What is an indirect affect of acid rain on Aquatic Life?
Acid rain burns the fish
Acid rain leaches Aluminum from soil which affects fish reproduction.
Acid rain makes the pH of the lake lower.
Acid rain makes fields acidic

6. Which animal is the most sensitive to acid rain?
Trout
Bass
Perch
Frogs
Clams

7. How does Acid rain affect buildings, structures and monuments?
Acid rain does not affect buildings.
Acid rain dissolves marble and limestone building materials and causes corrosion of metals.
Acid rain leaches nutrients from the soil.
Acid rain affects people’s lungs.

8. How does acid rain indirectly affect plants?
The acids burn the roots of plants
The acids lower the rate of germination of seeds
The acids leach nutrients from the soil
The acids make the soil acidic.

9. What are the major sources of air pollutants that cause acid rain?
Burning coal in power plants and industry and transportation
Burning coal only
Driving cars and transportation only
Burning wood

10. Sulfur and nitrogen oxides
What are the primary pollutants that cause acid rain?
Sulfur dioxide only
Nitrogen oxides only
Carbon dioxide
Sulfur and nitrogen oxides

11. Why is rain naturally slightly acidic?
Rain water is slightly acidic because sulfur dioxide in the air dissolves in rain water to form a weak acid.
Rain water is slightly acidic because carbon dioxide in the air dissolves in rain water to form a weak acid.
Rain water is slightly acidic because nitrogen dioxide in the air dissolves in rain water to form a weak acid.

12. Which process produces the most sulfur dioxide in the USA?
Coal power plants
Industry
Transport

13. Where is the acid deposition the most severe?
North Eastern USA
North Western USA
Southern USA
Northern USA

14. What are the secondary pollutants in acid rain?
Nitrogen oxides react to form nitric and sulfuric acids.
Nitrogen oxides react to form nitric and nitrous acids. Sulfur oxides react to from sulfuric and sulfurous acids.
Sulfur oxides react to form nitric, nitrous, sulfuric and sulfurous acids.

15. Evaluate the catalytic converter as a way to lower acid rain.
The catalytic converter reduces sulfur dioxide emissions
Nitrogen oxide emissions are lowered, but not 100%
Carbon dioxide emissions are lowered.
It is an inexpensive solution

16. Which are methods to reduce acid rain?
Catalytic converters, liming lakes, and alkaline scrubbers
Alkaline scrubbers, catalytic converters, removing sulfur from coal.
Liming lakes, catalytic converters, and removing sulfur from coal

17. Evaluate liming lakes as a way to mitigate the effects of acid rain.
The pH is restored, but some species do not return to the lake.
The pH can be raised, but not high enough to make a difference
The pH can be raised, but the process is expensive, and some species do not recover.

18. What substances are converted by the catalytic converter?
Carbon dioxide, oxygen, and unburned hydrocarbons are converted into carbon monoxide and water.
Carbon, unburned hydrocarbons, nitrogen oxides are converted into carbon dioxide, nitrogen and water.
Carbon monoxide, unburned hydrocarbons, nitrogen oxides are converted into carbon dioxide, nitrogen and water.

19. Which catalytic converter is most effective?
A B C

20. Which power source produces the most air pollution?
Nuclear
Hydroelectric
Wind
Solar
Coal
Natural gas
