35. Reviewing Main Ideas 1
Water Pollution
Water pollution comes from industrial discharge; runoff of pesticides and fertilizers from lawns and farms; and sewage.
Sewage from homes and businesses is purified before it is released back into a stream or river.

36. Reviewing Main Ideas 1
Water Pollution
National and international cooperation is necessary to reduce water pollution. In the United States, the 1990 Clean Water Act set up standards for sewage and wastewater-treatment facilities and for nonpoint sources.
Conserving water in your daily activities can help reduce water pollution.

37. Reviewing Main Ideas 2
Air Pollution
Exhaust from vehicles pollutes the air. Other sources of air pollution include power plants, fires and volcanoes.
Natural conditions, such as landforms and temperature inversions, can affect the ability of the atmosphere to disperse air pollutants.

38. Reviewing Main Ideas 2
Air Pollution
Polluted air can affect human health. Breathing particles, ozone, and acid rain can damage your lungs. Carbon monoxide can replace oxygen in your blood.
Air pollutants don’t have boundaries. They drift between states and countries. National and international cooperation is necessary to reduce the problem.

39. Question 1 Answer Why is particulate matter an air pollutant?
Chapter Review
Question 1
Why is particulate matter an air pollutant?
Answer
Particulate matter consists of fine particles of dust, pollen, ash, and other substances. The smaller the particles, the deeper they can travel into the lungs, causing breathing problems.

40. Question 2 Answer What is a scrubber?
Chapter Review
Question 2
What is a scrubber?
Answer
A scrubber is the part of a coal-burning power plant in which sulfur dioxide is removed from smoke before it leaves the plant. If sulfur dioxide is released into the atmosphere, it can form sulfuric acid and cause acid rain.

41. Question 3 Which of these has a pH above 7? A. acid B. base C. buffer

Question 3
Which of these has a pH above 7?
A. acid
B. base
C. buffer
D. neutral

42. Chapter Review
Answer
The answer is B. 7 on the pH scale is neutral; a substance with a pH above 7 is a base.

Chapter Review
Question 4
Water containing human waste is called __________.
A. effluent
B. fertilizer
C. point source pollution
D. sewage

44. Chapter Review
Answer

Question 2
At which point is it likely to be the easiest to reduce the amount of smog formed?

51. Standardized Test Practice
A. A
B. B
C. C
D. D

52. Standardized Test Practice
Answer
The answer is A. It is likely to be easier to control the amount of exhaust generated by cars than to control the process of smog formation in the atmosphere.

53. Standardized Test Practice
Question 3
This diagram illustrates how the atmosphere can influence the formation of smog. What is the name of this phenomenon?

54. D. temperature inversion
Standardized Test Practice
A. air blanketing
B. normal condition
C. pH intolerance
D. temperature inversion

55. Standardized Test Practice
Answer
The answer is D. During a temperature inversion, warm air overlies cool air, and air pollutants can’t be dispersed.
