13. Section 1-5 Advertising is one of the major service industries in the United States. In 1997, U.S. companies spent more than $187 billion to advertise their products or services. About one-quarter of this amount is spent on television commercials. The next biggest markets for advertisements are local newspapers and direct mail.

14. Section 1-6 Economic Activities Both the United States and Canada have free market economies, in which people can own, operate, and profit from their own businesses. Both economies were once primarily agricultural but are now industrial and service economies. (pages 157–159)

15. Section 1-7 Click the mouse button or press the Space Bar to display the information. Economic Activities (cont.) One billion acres (405,000,000 ha) in the United States and 167 million acres (67,583,000 ha) in Canada are used for agriculture.  Only a small percentage of Americans and Canadians work as farmers, because of the high cost of farming, the hard work involved, and unpredictable consumer demand. Agriculture Farming in the region is primarily commercial and large-scale.  (pages 157–159)

16. Section 1-8 Click the mouse button or press the Space Bar to display the information.

19. Section 1-11 How does the region’s physical geography relate to its agricultural production? Because the countries are so large and spacious, large farms and ranches are possible. There is plenty of room in the West for cattle ranches. The temperate climate of the United States is ideal for farming, as are the rich soils of both countries’ midsections. Major rivers and the Great Lakes provide transportation for farm products. Click the mouse button or press the Space Bar to display the answer. Economic Activities (cont.) (pages 157–159)

57. Section 2-13 Automobiles are a major source of pollution, yet most people in this region continue to prefer automobile transportation over mass transit. Why might they do so, and how would you meet this challenge? Possible answers: Many people like the convenience of being able to get from place to place quickly and whenever they want. Some people need their cars to get to work. Bicycles are not practical for people who have to take their children somewhere. Not everyone lives in an area served by public transit. People in the United States often do not live near the places they need to go, so they have to drive.

62. Section 2-18 Critical Thinking Analyzing Information Why is it important for Canada and the United States to work together to reduce pollution? It is important for Canada and the United States to work together to reduce pollution because wind and water carry pollution across borders. Click the mouse button or press the Space Bar to display the answer.

63. Section 2-19 Click the mouse button or press the Space Bar to display the answer. Critical Thinking Drawing Conclusions Why are more metropolitan areas of the United States and Canada beginning to experience smog? Metropolitan areas are beginning to experience smog because automobile exhaust gases and industrial emissions are increasing.

64. Section 2-20 Click the mouse button or press the Space Bar to display the answer. Critical Thinking Identifying Cause and Effect What are the short-term and long-term effects of water pollution on people and the environment? Short-term effects include poisoning the food chain from the smallest animals on up, including endangering the health of humans. Long-term effects include eutrophication, which eventually can turn lakes into swamps and then into dry land.

65. Section 2-21 Analyzing Maps Place Study this map of acid rain. Which parts of the region have the greatest concentration of acid rain? Why? Eastward winds carry the rain from the Midwest’s coal-burning plants to the area around Lake Erie and to eastern Ohio and western Pennsylvania.

88. GeoFact 1 Route 66, the celebrated road from Chicago to southern California, lost much of its traffic and its allure after a number of more modern highways were built in the 1970s. The 2,448-mile (3,940-km) route is making a comeback, however. The U.S. Department of the Interior will spend $10 million by 2010 to preserve Route 66.

89. GeoFact 2 The Wildfires of 2000 scorched more than 6 million acres of land in the western United States, much of it in Montana and Idaho. Rehabilitating the burned land involves using bales of hay and coconut fiber mats to prevent soil erosion and reseeding with native prairie grasses to replace the nonnative cheatgrass, which dries out quickly and provides ample fuel for wildfires.

90. Interdisciplinary Connection 1 Agronomy Climatology Click on a hyperlink to view the corresponding slide.

91. Interdisciplinary Connection 1a Agronomy is the branch of agricultural science that deals with the study of crops and soils. Agronomists research methods of crop rotation, irrigation, plant breeding, and weed control. They work to improve soil and increase crop production.

92. Interdisciplinary Connection 1b Climatology A computer model called the Integrated Biosphere Simulator analyzes interactions among humans, the earth’s atmosphere, and the global ecosystem. Climatologists study land use to see how commercial agricultural practices, for example, can alter ecosystems, which in turn can alter the atmosphere. Replacing forests with pasture results in a drier climate because a pasture does not return as much water to the atmosphere as does a forest.

93. FYI 1 High-Tech Industry Highway System Click on a hyperlink to view the corresponding slide.

94. FYI 1a High-Tech Industry The strong U.S. economy of the 1990s made central Texas a leader in the high- tech industry. One of the world’s largest direct-sale computer producers is headquartered in Austin, Texas, as are several computer chip manufacturing firms. Together, these companies employ tens of thousands of people. Their presence, in turn, has an impact on the state’s shipping industry. Hundreds of trucks are dispatched daily with the finished products.

95. FYI 1b Highway System The Federal Interstate Highway System was started in the 1950s during the Eisenhower administration. Under this system, even numbered highways run east and west; odd- numbered highways run north and south.

96. FYI 2 Yew Trees This valuable tree, which grows in the Pacific Northwest, was viewed as a trash tree until a cancer-battling chemical called taxol was discovered in the bark of the tree. Taxol may cause remission in some patients.

98. SkillBuilder 1 Interpreting a Climate Map Climate helps determine how people live, work, dress, and play in a particular region. People on different continents may share similar climates. By reading a climate map, you can discover these similarities and differences among regions.

99. SkillBuilder 2 Learning the Skill A climate map shows the climate zones of a region. Latitude, temperature, precipitation, altitude, wind patterns, and nearness to oceans help determine the climate of a region. Variation in precipitation also creates different types of climates, such as rain forest (very wet), desert (very dry), and savanna (wet and dry seasons). Interpreting a Climate Map
