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. For lubricating motors






2. 22% of energy consumed in the U.S. comes from the burning of natural gas.






3. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






4. Structural traps and stratigraphic traps






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






6. Fuel for jets and tractors






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






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






9. For heating - cooking - and making plastics






10. Length of time global natural gas supply is expected to last.






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






12. 1 Btu = 1055 J






13. Peat - formed from plants.






14. Heat - pressure - dearth of oxygen






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






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

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






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






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






20. Soft coal - with the highest energy content






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






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






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






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






25. Salt or cemented sandstone






26. Oil with little or no sulfur






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






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






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






30. 125000 Btu per gallon






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






32. Fuel for trucks






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






34. 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.






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






36. Marine shale - limestone - or oil shale






37. 1 Therm = 100000 Btu






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






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






41. Intermediate between hard coal and peat






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






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






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






45. Soot - sulfur oxides - nitrogen oxides - mercury






46. Energy






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






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






49. Consist of clay - sand - water and bitumen - a type of oil.






50. Traps formed by folding or faulting of rock layers
