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. Marine shale - limestone - or oil shale






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






3. 1 Btu = 1055 J






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






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






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






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






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






9. Natural gas that has been compressed and stored at very high pressure in strong containers.






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






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






12. Structural traps and stratigraphic traps






13. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






14. 1 Btu = 2.931x10-4 kWh






15. 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.






16. Unrefined oil. May appear thick and brown or black - or clear.






17. Fuel for cars






18. Fuel for trucks






19. Refined natural gas that contains pure methane.






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






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






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






23. Hard coal - with the second highest energy content






24. The quantity of oil (or other energy resource) that exists and can be recovered under current operating and economic conditions.






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






26. Soot - sulfur oxides - nitrogen oxides - mercury






27. A mixture of of hydrocarbons and organic compounds






28. Intermediate between hard coal and peat






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






30. The ratio of the energy return to the energy invested.






31. Soft coal - with the highest energy content






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






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






34. For heating - cooking - and making plastics






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


36. Traps formed by folding or faulting of rock layers






37. Oil with little or no sulfur






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






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






40. A mixture of hydrocarbons found in naturally occurring underground reservoirs






41. For lubricating motors






42. Natural gas that flows to the surface from an underground reservoir when a well is dug.






43. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






46. Heat - pressure - dearth of oxygen






47. Energy






48. A layer of cap rock that confines the oil and gas - must be impermeable.






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






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