Accepted Answer

A)   Ferrel cells
B)   equatorial high-pressure belts
C)   Hadley cells
D)   subtropical low-pressure belts

Question 12

A)   absorbs harmful ultraviolet radiation.
B)   can cause respiratory ailments such as asthma.
C)   is an example of a secondary pollutant.
D)   All of these are correct.

Question 13

Soot from forest fires, smoke from cigarettes, and photochemical smog are all examples of

Accepted Answer

A)   primary pollutants.
B)   secondary pollutants.
C)   air pollution.
D)   volatile organic compounds.

Question 14

Describe the difference between primary and secondary pollutants and identify the specific pollutants that are involved with acid deposition. In addition, explain why the effects of acid deposition are more severe along the East Coast compared to the rest of the United States.

Accepted Answer

Primary pollutants emit directly from a source, whereas secondary pollutants are the product of reactions occurring in the atmosphere. The primary pollutants of sulfur dioxide and nitrogen oxides, which emitted from coal-fired power plants, automobile exhaust, and a range of agricultural and industrial processes, react with water vapor in the atmosphere to form the secondary pollutants of sulfuric acid and nitric acid. Precipitation of these acidic solutions is known as acid deposition, or "acid rain." The prevailing wind and precipitation patterns in the continental United States carry pollutants hundreds of miles from coal-fired power plants and other sources in the Midwest to the East Coast and many areas in the northeastern United States and in Canada.

Question 15

Which factor associates with increased temperature at Earth's surface?

Accepted Answer

A)   a lower latitude relative to the equator and poles
B)   a higher altitude relative to sea level
C)   a coastal area relative to an inland area
D)   All of these are correct.

Question 16

Most man-made satellites orbit in the 	, the top layer of the atmosphere.

Accepted Answer

A)   mesosphere
B)   thermosphere
C)   troposphere
D)   stratosphere

Question 17

Select the secondary pollutant.

Accepted Answer

A)   ground-level ozone
B)   volatile organic compounds
C)   nitrogen oxides
D)   particulate matter
