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. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






4. Traps formed by folding or faulting of rock layers






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






6. 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.






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






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






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






10. Heat - pressure - dearth of oxygen






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






12. Refined natural gas that contains pure methane.






13. Fuel for cars






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






15. Fuel for jets and tractors






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






17. 1 Btu = 2.931x10-4 kWh






18. Intermediate between hard coal and peat






19. 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.






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






21. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






22. Salt or cemented sandstone






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






24. Soft coal - with the highest energy content






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






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






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






28. For lubricating motors






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






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






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






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






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






34. Energy






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






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






37. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






39. Peat - formed from plants.






40. A mixture of of hydrocarbons and organic compounds






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






42. Marine shale - limestone - or oil shale






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






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

45. For heating - cooking - and making plastics






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






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






48. Structural traps and stratigraphic traps






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






50. Fuel for trucks
