A.the air

B.the soil

C.the water

D.All of these

E.None of these

Question 133

Arrange these in the correct order, starting with the layer closest to the ground:

1. ozone layer    2. stratosphere   3. troposphere

A.3, 1, 2

B.2, 3, 1

C.1, 2, 3

D.The layers mix freely, so there is no distinction.

E.None of these

Question 134

Does the concentration of chlorine in drinking water tend to increase or decrease as it leaves the water treatment plant and disperses into the community? Why?

A.Increases. As the chlorine reacts with the bacteria in the water, more chlorine is produced.

B.Increases. As the water evaporates the chlorine concentration would increase in the remaining water.

C.Decreases. Evaporative processes and reaction with organic bacteria would decrease the chlorine concentration.

D.Neither. The chlorine concentration in the water does not vary as the water is dispersed into the community.

Question 135

Why are seasonal fluctuations in atmospheric CO2 much more pronounced in the northern hemisphere compared to the southern hemisphere?

A.The trees and other photosynthetic plants absorb atmospheric carbon dioxide in summer in the northern hemisphere but lose their leaves in fall and winter, and photosynthesis stops.

B.During the fall and winter in the northern hemisphere decay of the organic matter generates carbon dioxide, which increases the atmospheric CO2 levels by the spring.

C.Both The trees and other photosynthetic plants absorb atmospheric carbon dioxide in summer in the northern hemisphere but lose their leaves in fall and winter, and photosynthesis stops and During the fall and winter in the northern hemisphere decay of the organic matter generates carbon dioxide, which increases the atmospheric CO2 levels by the spring are true.

D.CO2 production is more limited in the area of our planet's largest land masses, which are located in the southern hemisphere.

Question 136

How is most of the water consumed by individuals in the United States actually used?

A.We rinse it down the sink, tub, or toilet.

B.We drink it.

C.We use it to water our lawns.

D.It evaporates.

E.None of these

Question 137

Why do nutrient ions like nitrate and phosphate often lead to a decrease in aquatic life?

A.Algae grow rapidly and use up all the oxygen.

B.Aerobic bacteria grow rapidly and use up all the oxygen.

C.Anaerobic bacteria grow rapidly and use up all the oxygen.

D.All of these

E.None of these

Question 138

How are the disinfecting properties of ultraviolet light and ozone similar to each other?

A.Both provide residual protection against pathogens.

B.Both are relatively effective at destroying bacteria but not viruses.

C.Neither provides residual protection against pathogens.

D.Both are relatively effective at destroying viruses but not bacteria.
