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. Marine shale - limestone - or oil shale






2. Salt or cemented sandstone






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






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






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






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






8. Fuel for trucks






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






10. Structural traps and stratigraphic traps






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






12. Heat - pressure - dearth of oxygen






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






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






15. 125000 Btu per gallon






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






17. 1 Btu = 2.931x10-4 kWh






18. Energy






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






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

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






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






23. 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.






24. Soft coal - with the highest energy content






25. Peat - formed from plants.






26. Refined natural gas that contains pure methane.






27. For lubricating motors






28. Fuel for cars






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






30. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






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






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






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






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






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






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






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






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






41. Oil with little or no sulfur






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






43. Fuel for jets and tractors






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






45. A mixture of of hydrocarbons and organic compounds






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






47. Intermediate between hard coal and peat






48. 1 Therm = 100000 Btu






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






50. Hard coal - with the second highest energy content
