34 True/False questions

  1. meltdown (of nuclear reactor)The part of a nuclear power plant where the fission reactions occur.

          

  2. coal rankA measurement of the carbon content of coal; higher-rank coal forms at higher temperatures.

          

  3. oreRock containing native metals or a concentrated accumulation of ore minerals.

          

  4. coalAn organic sedimentary rock formed from plant debris.

          

  5. MetalAn organic sedimentary rock formed from plant debris.

          

  6. Oil AgeThe period of human history, including our own, so named because the economy depends on oil.

          

  7. cementMineral material that precipitates from water and fills the spaces between grains, holding the grains together.

          

  8. peatCompacted and partially decayed vegetation accumulating beneath a swamp.

          

  9. mineral resourcesSomething that can be used to produce work; in a geologic context, a material (such as oil, coal, wind, flowing water) that can be used to produce energy.

          

  10. nuclear wasteThe part of a nuclear power plant where the fission reactions occur.

          

  11. oil shaleThe period of human history, including our own, so named because the economy depends on oil.

          

  12. resourceRock containing native metals or a concentrated accumulation of ore minerals.

          

  13. coal gasificationA measurement of the carbon content of coal; higher-rank coal forms at higher temperatures.

          

  14. gas hydrateA measurement of the carbon content of coal; higher-rank coal forms at higher temperatures.

          

  15. nuclear reactorRadioactive materials produced in a nuclear reactor.

          

  16. photosynthesisThe process during which chlorophyll-containing plants remove carbon dioxide from the atmosphere, form tissues, and expel oxygen back to the atmosphere.

          

  17. greenhouse effectThe trapping of heat in the Earth's atmosphere by carbon dioxide and other greenhouse gases, which absorb infrared radiation; somewhat analogous to the effect of glass in a greenhouse.

          

  18. coalbed methaneNatural gas produced during the diagenesis of coal.

          

  19. oil windowThe narrow range of temperatures under which oil can form in a source rock.

          

  20. trapIn the context of hydrocarbons, a trap is a geologic configuration that accumulates and holds oil underground.

          

  21. energyMineral material that precipitates from water and fills the spaces between grains, holding the grains together.

          

  22. ore depositAn economically significant accumulation of ore.

          

  23. salt domeA rising bulbous dome of salt that bends up the adjacent layers of sedimentary rock.

          

  24. permeabilityThe total volume of empty space (pore space) in a material, usually expressed as a percentage.

          

  25. hydrocarbon reserveAn accumulation of accessible oil and gas.

          

  26. hydrocarbonThe waxy molecules into which the organic material in shale transforms on reaching about 100 ¡C. At higher temperatures, kerogen transforms into oil.

          

  27. KerogenThe waxy molecules into which the organic material in shale transforms on reaching about 100 ¡C. At higher temperatures, kerogen transforms into oil.

          

  28. energy resourceThe minerals extracted from the Earth's upper crust for practical purposes.

          

  29. geothermal energyHeat and electricity produced by using the internal heat of the Earth.

          

  30. reservoir rockA supply of useable material.

          

  31. fossil fuelAn energy resource such as oil or coal that comes from organisms that lived long ago, and thus stores solar energy that reached the Earth then.

          

  32. tar sandSandstone reservoir rock in which less viscous oil and gas molecules have either escaped or been eaten by microbes, so that only tar remains.

          

  33. biofuelRock containing native metals or a concentrated accumulation of ore minerals.

          

  34. porosityThe waxy molecules into which the organic material in shale transforms on reaching about 100 ¡C. At higher temperatures, kerogen transforms into oil.
