Chapter 5.2 Energy Resources Key Terms
Across
- 3. energy by the use of wind turbines to generate electricity.
- 4. energy generated in ways that do not deplete natural resources or harm the environment, especially by avoiding the use of fossil fuels and nuclear power
- 5. make full use of and derive benefit from (a resource)
- 6. a natural resource that cannot be readily replaced (nonrenewable) by natural means at a pace quick enough to keep up with consumption.
- 7. any natural resource that can replenish itself naturally over time, such as wood or solar energy; also called renewable energy
- 10. a natural fuel such as coal, oil, or gas, formed in the geological past from the remains of living organisms
- 11. An open excavation or pit from which stone is obtained by digging, cutting, or blasting.
- 13. a kind of air pollution, originally named for the mixture of smoke and fog in the air. Results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulfur dioxide. A problem in a number of cities and continues to harm human health.
- 15. a resource of economic value that cannot be readily replaced by natural means on a level equal to consumption. Example: oil, natural gas and coal
- 16. the quality of not being harmful to the environment or depleting natural resources, and thereby supporting long-term ecological balance
- 17. form of energy produced by the natural rise and fall of tides.
- 18. HydroElectric Power; a form of energy generated by the conversion of free-falling water to electricity
- 19. a resource that can be used over and over, but must go through a process to prepare it for re-use
Down
- 1. a natural resource that can be replenished (renewable) by natural means such as solar, wind, geothermal, HEP
- 2. large strips of land are excavated in order to extract materials without subsurface tunneling
- 6. the process of injecting liquid at high pressure into subterranean rocks, boreholes, etc. so as to force open existing fissures and extract oil or gas
- 8. heat energy from the earth- geo (earth) + thermal (heat) which originates from the formation of radioactive decay of material inside the earth. These underground reservoirs of steam and hot water can be tapped to generate electricity.
- 9. liquid fuels produced from renewable biological sources (biomass including wood, bioethanol and biogas from plants and algae)
- 12. the amount of a substance which can be extracted from the earth with current technology at current prices. Typically much smaller than the resource.
- 14. form of energy that converts sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate sunlight solar radiation.
- 15. the energy released by nuclear reactions in the nucleus of atoms such as uranium.
