7Question: What natural resources can be found in North America? SECTION 3Natural ResourcesQuestion:What natural resources can be found in North America?
8Agricultural resources SECTION 3Natural ResourcesAgricultural resources• large area• good climates for farming• fertile soils• provide enough food to feed population and leave a surplusForest resources• large forests and tree farms• produce wood for lumber, newsprint, pulpwood, and other forest products• leading producers and exportersWater resources• allow for irrigation and hydroelectricity production• rich fisheries along coastsResources of North AmericaMineral resources• nickel, zinc, uranium, lead, copper, gold, and silver in Canada• iron, copper, lead, zinc, gold silver, and other minerals in United StatesEnergy resources• huge coal reserves• major oil producer, but still must import• rich in natural gas
9Chapter Wrap-Up CHAPTER 7 1. What physical process forms barrier islands? Where are they found in North America?2. What evidence of tectonic forces will you find in western areas of the United States and Canada?3. What can happen when different air masses come in contact with one another over the Great Plains?4. What major factors influence climates in the United States? How does nearness to the Great Lakes and the Atlantic Ocean influence the humid continental climate region of the northeastern Untied States?5. About 25 percent of the world’s reserves of which energy resource are found in the United States?
