Natural Resources 10.1 Natural resources support human activity. 10.2 CHAPTER NEW CHAPTER Natural Resources the BIG idea Society depends on natural resources for energy and materials. 10.1 Natural resources support human activity. 10.2 Resources can be conserved and recycled. 10.3 Energy comes from other natural resources. CHAPTER OUTLINE CHAPTER RESOURCES

Natural resources support human activity. 10.1 Natural resources support human activity. Renewable Resources • Sunlight • Wind • Water • Trees, other plants • Plant and animal waste Examples of Products • Lumber • Paper • Clothing natural resource renewable resource Energy nonrenewable resource fossil fuel Nonrenewable Resources • Coal • Oil, natural gas • Uranium • Minerals, rocks Examples of Products • Fuels • Plastics • Electronic goods CHAPTER RESOURCES SECTION OUTLINE

10.1 natural resource Natural resources support human activity. renewable resource Any type of matter or energy from Earth’s environment that humans use to meet their needs. nonrenewable resource fossil fuel CHAPTER RESOURCES KEY CONCEPT SUMMARY

10.1 renewable resource Natural resources support human activity. A natural resource that can be replaced in nature at about the same rate as it is used. nonrenewable resource fossil fuel CHAPTER RESOURCES KEY CONCEPT SUMMARY

nonrenewable resource 10.1 Natural resources support human activity. natural resource nonrenewable resource renewable resource A resource that exists in a fixed amount or is used up more quickly than it can be replaced in nature. nonrenewable resource fossil fuel CHAPTER RESOURCES KEY CONCEPT SUMMARY

10.1 Natural resources support human activity. natural resource fossil fuel renewable resource Fuel formed from the remains of prehistoric organisms that is burned for energy. Fossil fuels burn easily and produce a lot of heat. They are used to run most of the power plants that generate electricity. nonrenewable resource fossil fuel CHAPTER RESOURCES KEY CONCEPT SUMMARY

Resources can be conserved and recycled. 10.2 Resources can be conserved and recycled. People can conserve natural resources by reducing waste at the source and reusing products. conservation recycling This 1.9 liter (64 fl oz) carton has 1088 sq cm of packaging. Eight travel-size containers provide 1.9 liters (64 fl oz) but have 2720 sq cm of packaging. CHAPTER RESOURCES SECTION OUTLINE

Resources can be conserved and recycled. 10.2 Resources can be conserved and recycled. People can conserve natural resources by reducing waste at the source and reusing products. conservation Recycling helps people recover materials, reduce the use of fossil fuels, and protect the environment and human health. recycling CHAPTER RESOURCES SECTION OUTLINE

10.2 conservation Resources can be conserved and recycled. recycling The process of saving or protecting a natural resource. CHAPTER RESOURCES KEY CONCEPT SUMMARY

5.2 recycling Resources can be conserved and recycled. conservation recycling recycling The reusing of materials that people would otherwise throw away, such as paper, glass, plastics, and certain metals. CHAPTER RESOURCES KEY CONCEPT SUMMARY

Energy comes from other natural resources. 10.3 Energy comes from other natural resources. Nuclear power plants uranium Geothermal plants Earth’s heat nuclear fission hydroelectric energy Electrical Energy geothermal energy Hydroelectric dams flowing water Wind farms moving air biomass hydrogen fuel cell Solar cells sunlight Biomass stations plant and animal waste Hydrogen fuel cells hydrogen CHAPTER RESOURCES SECTION OUTLINE

SIMULATION CLASSZONE.COM VISUALIZATION Watch a hydrogen fuel cell in action. geothermal energy biomass hydrogen fuel cell CHAPTER RESOURCES SECTION OUTLINE

10.3 nuclear fission Energy comes from other natural resources. hydroelectric energy The process of splitting the nuclei of radioactive atoms, which releases huge amounts of energy mainly in the form of radiation and heat energy. geothermal energy biomass hydrogen fuel cell In the glossary, Science SPEng GlossaryEditB.doc, it is listed as nuclear fission. CHAPTER RESOURCES KEY CONCEPT SUMMARY

10.3 hydroelectric energy Energy comes from other natural resources. nuclear fission hydroelectric energy hydroelectric energy Electricity that is generated by the conversion of the energy of moving water. geothermal energy biomass hydrogen fuel cell CHAPTER RESOURCES KEY CONCEPT SUMMARY

10.3 geothermal energy Energy comes from other natural resources. nuclear fission geothermal energy hydroelectric energy Heat energy that originates from within Earth and drives the movement of Earth’s tectonic plates. Geothermal energy can be used to generate electricity. geothermal energy biomass hydrogen fuel cell CHAPTER RESOURCES KEY CONCEPT SUMMARY

10.3 biomass Energy comes from other natural resources. nuclear fission biomass hydroelectric energy Organic matter that contains stored energy from sunlight and that can be burned as fuel. geothermal energy biomass hydrogen fuel cell CHAPTER RESOURCES KEY CONCEPT SUMMARY

10.3 hydrogen fuel cell Energy comes from other natural resources. nuclear fission hydrogen fuel cell hydroelectric energy A device that uses hydrogen and oxygen to produce electricity. The byproducts are heat and water. geothermal energy biomass hydrogen fuel cell CHAPTER RESOURCES KEY CONCEPT SUMMARY

Natural resources support human activity. 10.1 Natural resources support human activity. I. Natural resources support human activity. natural resource A. Natural resources provide materials and energy. renewable resource 1. Renewable Resources nonrenewable resource 2. Nonrenewable Resources fossil fuel B. Fossil fuels supply most of society’s energy. 1. Coal 2. Oil and Natural Gas C. Fossil fuels, minerals, and plants supply materials for modern products. CHAPTER RESOURCES KEY CONCEPT SUMMARY

Resources can be conserved and recycled. 10.2 Resources can be conserved and recycled. II. Resources can be conserved and recycled. conservation A. Conservation involves reducing waste and reusing natural resources. recycling B. Recycling involves recovering and extending natural resources. CHAPTER RESOURCES KEY CONCEPT SUMMARY
