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






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






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






4. For lubricating motors






5. 1 Btu = 2.931x10-4 kWh






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






7. A mixture of of hydrocarbons and organic compounds






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






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






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






11. 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.






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






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






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






15. Oil with little or no sulfur






16. Heat - pressure - dearth of oxygen






17. Soft coal - with the highest energy content






18. Intermediate between hard coal and peat






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






20. Fuel for cars






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






22. Refined natural gas that contains pure methane.






23. Soot - sulfur oxides - nitrogen oxides - mercury






24. Fuel for trucks






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






26. Salt or cemented sandstone






27. For heating - cooking - and making plastics






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






29. 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.






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






31. 1 Btu = 1055 J






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






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






34. Hard coal - with the second highest energy content






35. 1 Therm = 100000 Btu






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






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






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

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






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






41. Traps formed by folding or faulting of rock layers






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






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






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






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






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






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






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






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






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