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 layer of sediment where oil and gas originate.






2. Refined natural gas that contains pure methane.






3. Fuel for cars






4. Soot - sulfur oxides - nitrogen oxides - mercury






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






6. Structural traps and stratigraphic traps






7. 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.






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






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






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






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






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






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






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






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






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






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






18. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






19. Marine shale - limestone - or oil shale






20. Peat - formed from plants.






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






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






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






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






25. 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.






26. A mixture of of hydrocarbons and organic compounds






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






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






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






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






31. Energy






32. Intermediate between hard coal and peat






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






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






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






36. Soft coal - with the highest energy content






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






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






39. An arch of stratified rock - an important geological feature that may be associated with reserves of oil - a type of structural trap.






40. For heating - cooking - and making plastics






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






42. For lubricating motors






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






44. Hard coal - with the second highest energy content






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






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






47. 1 Btu = 2.931x10-4 kWh






48. Fuel for trucks






49. Oil with little or no sulfur






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