Name: Period: Chapter 7: Natural Resources Renewable or Nonrenewable? 1. Define Renewable Natural Resource: 2. Define Nonrenewable Natural Resource: 3. Which nonrenewable resource is nonrenewable because, although it can be made again, it takes millions of years to make? 4. What are some nonrenewable resources that can be reused? 5. On the average, how many pounds of minerals are used per person in the U.S.? In the chart below, identify whether each energy resource is renewable of nonrenewable (R or NR). (R or Resource NR)? ______ Wind Power (using windmills to generate electricity) ______ Tidal Power (using the energy of moving water from tides to generate electricity) ______ Hydrothermal Power (hot water from hot springs) ______ Geothermal Power (heating up water by using heat from inside the Earth) ______ Coal Power (using heat from burning coal to heat water and generate electricity) Nuclear Power (using the heat from the decay of radioactive elements to generate electricity) ______ Burning Wood (burning wood for heat, or to generate hot water for steam power or electricity) ______ ______ Burning Trash to generate heat for electricity production. ______ Burning Organic Waste (burning animal waste to produce heat) ______ Burning Methane from buried, rotting trash or decaying animal waste to produce heat. ______ Burning oil to produce heat, electricity, or engine power ______ Burning natural gas to produce heat or electricity ______ Solar Power (using energy from the Sun to heat water to generate electricity or for heat) ______ Hydroelectric Power (using the energy of flowing or falling water to generate electricity) Earth’s Minerals 6. All economically important metallic elements are obtained from _____________. 7. A “Native Metal” is: 8. Examples of native metals include ______________ and ______________. 9. A rock that contains valuable minerals that are chemically combined with the rock is called a ______________. 10. Examples of the above type of mineral include ______________ and _____________. 11. Examples of industrially important mineral resources, if not necessarily economically valuable per pound, that are separated from surrounding materials by physical means include ______________, ______________ and ______________. Supply and Demand 12. The known deposits of a particular mineral that are worth mining is called the ______________ of that mineral. 13. Ores deep in the ground are normally removed by: 14. Ores close to the surface are generally removed by: 15. Some examples of metals that must be nearly entirely imported in the U.S. include: 16. Some uses of Iron: 17. Some uses of Copper: 18. Some uses of Zinc: 19. Some uses of Lead: 20. Reducing the demand for a mineral does what for the length of time that it will be available? Nonrenewable Resources 21. What percentage of America’s energy consumption comes from nonrenewable energy sources? 22. These resources include ______________, ______________, ______________ and ______________. 23. Fossil fuels include ______________, ______________ and ______________. 24. Why are fossil fuels nonrenewable? 25. What is Coal used for? 26. Metamorphic Coal is called ______________. 27. Which type of Coal releases the greatest amount of energy per pound? 28. Since the amount of oil found in oil shale and tar sands is much greater than current oil reserves, why is this resource not being used more? 29. Which fossil fuel is the least expensive? 30. An example of a metallic element used for fuel is ______________. 31. Uranium is used to generate ______________ in nuclear power plants. 32. The fission of one gram of Uranium releases as much energy as doing what two things? Renewable Natural Resources 33. The most widely used renewable natural resources include ______________, ______________, ______________ and ______________. 34. Electricity produced by water power is called: 35. How can tides be harnessed to create electricity? 36. Where would windmills be effective sources of energy production? 37. Energy from the Sun is called ______________. 38. Where would solar power not be a very good source of energy? 39. Heat from the Earth’s interior is called: 40. How is geothermal converted into electrical energy? Environmental Issues 41. How long does it take strip-mined land to recover? 42. Why is surface run-off from mines hazardous? 43. Identify two negative aspects of nuclear power. 44. Identify a negative aspect of energy production using coal. 45. Identify two potential downsides to hydroelectric power.
