CSET Earth Resources Fossil Fuels

Subjects : cset, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The ratio of the energy return to the energy invested.






2. Reserves that are not as well known or characterized as proved reserves






3. Sludge (rich in organic matter) that accumulates at the bottom of lakes or oceans






4. Traps formed by folding or faulting of rock layers






5. Hard coal - with the second highest energy content






6. Crude oil that contains a mixture of hydrocarbons that are relatively dense






7. Fuel for trucks






8. Natural gas that has been cooled to a liquid to store and transport.






9. Length of time US coal reserves are expected to last...






10. An emergency supply of crude oil created by the US government following the oil embargo of 1973-1974. Contains more than 700 million barrels.






11. A layer of relatively porous and permeable rock in which the oil and gas coming up from the source rock can reside.






12. Crude oil that contains a mixture of hydrocarbons that are relatively less dense






13. Intermediate between hard coal and peat






14. Coal is converted to a gas - making it easier to remove impurities.






15. Raw material in the production of pain and fertilizer - steel - glass - paper - and other products.






16. A type of sedimentary rock that - when heated - releases hydrocarbons.






17. Energy to raise the temperature of 1 lb of water by 1 degree F at 1 atm.






18. Formed by changes in rock type or sedimentary features that create a space where hydrocarbons are confined by impermeable layers






19. Burns coal at lower temperatures - reducing the production of nitrogen oxides - and making it easier to remove sulfur oxides.






20. Peat - formed from plants.






21. Fraction of California's total energy requirements provided by natural gas


22. Heat - pressure - dearth of oxygen






23. Remaining oil is made more fluid so as to bring it up more easily. Brings up another 5-15% of the supply - but is much more costly.






24. Fuel for cars






25. 1 Btu = 2.931x10-4 kWh






26. Soft coal - with the highest energy content






27. The process of drilling for oil and pumping it out. Accounts for 5-15% of the supply.






28. 1 Therm = 100000 Btu






29. Natural gas that exists in other forms - making it more difficult to extract.






30. For heating - cooking - and making plastics






31. Reserves that can reasonably be expected to exist based on geological evidence and projections from proved reserves.






32. Source rock under a reservoir bed - under a trap.






33. Oil with little or no sulfur






34. The layer of sediment where oil and gas originate.






35. Methane produced by the action of microorganisms on waste in landfills






36. Salt or cemented sandstone






37. A mixture of of hydrocarbons and organic compounds






38. Refined natural gas that contains pure methane.






39. Water or gas is injected into the reservoir to increase the pressure - bringing the oil to the surface. Begins when the oil no longer rises naturally to the surface. Accounts for 15-45% of the supply.






40. For lubricating motors






41. Unrefined mixture of methane - ethane - propane - and butane.






42. Phytoplankton and zooplankton that accumulated in marine sediments beginning 300 million years ago






43. An industrial fuel - also used to make petroleum products






44. Under layers of sedimentary rock like limestone and shale - and over sandstone.






45. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






46. Soot - sulfur oxides - nitrogen oxides - mercury






47. Cubic feet - volume - used when gas is at normal temperature and pressure - Dollars per volume in cubic feet - price






48. Structural traps and stratigraphic traps






49. Generate electricity - produce steel - plastics - synthetic fibers - fertilizers - and medicines






50. Fuel for jets and tractors
