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






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






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






4. Fuel for jets and tractors






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






6. Oil with little or no sulfur






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






8. Structural traps and stratigraphic traps






9. Soft coal - with the highest energy content






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






11. 1 Btu = 2.931x10-4 kWh






12. Heat - pressure - dearth of oxygen






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






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






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






16. Marine shale - limestone - or oil shale






17. For lubricating motors






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






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






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






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






23. Peat - formed from plants.






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






25. Fuel for trucks






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






27. Refined natural gas that contains pure methane.






28. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






30. Salt or cemented sandstone






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






32. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






35. For heating - cooking - and making plastics






36. Hard coal - with the second highest energy content






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






38. A mixture of of hydrocarbons and organic compounds






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






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






41. 1 Btu = 1055 J






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

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






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






45. Intermediate between hard coal and peat






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






47. Energy






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






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






50. 1 Therm = 100000 Btu
