Acid Rain Clicker Quiz
2
What is acid precipitation?

1. Any precipitation with a pH of 5.6
2. Precipitation with a pH of less that 5.6
3. Precipitation that is not neutral
4. 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

Which animal is the most sensitive to acid rain?

1. Trout
2. Bass
3. Perch
4. Frogs
5. 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 peoples 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

• 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?

1. Coal power plants
2. Industry
3. Transport

13
Where is the acid deposition the most severe?

1. North Eastern USA
2. North Western USA
3. Southern USA
4. 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?

1. Catalytic converters, liming lakes, and alkaline
   scrubbers
2. Alkaline scrubbers, catalytic converters,
   removing sulfur from coal.
3. Liming lakes, catalytic converters, and removing
   sulfur from coal

17
Evaluate liming lakes as a way to mitigate the
effects of acid rain.

1. The pH is restored, but some species do not
   return to the lake.
2. The pH can be raised, but not high enough to make
   a difference
3. 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?

1. Carbon dioxide, oxygen, and unburned hydrocarbons
   are converted into carbon monoxide and water.
2. Carbon, unburned hydrocarbons, nitrogen oxides
   are converted into carbon dioxide, nitrogen and
   water.
3. 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?

1. Nuclear
2. Hydroelectric
3. Wind
4. Solar
5. Coal
6. Natural gas
