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. An industrial fuel - also used to make petroleum products






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






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






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






5. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






8. Salt or cemented sandstone






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






10. Traps formed by folding or faulting of rock layers






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






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






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






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






15. Energy






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






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






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






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






20. For heating - cooking - and making plastics






21. 1 Btu = 1055 J






22. For lubricating motors






23. Fuel for jets and tractors






24. Refined natural gas that contains pure methane.






25. Structural traps and stratigraphic traps






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






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






28. 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.






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






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






31. Oil with little or no sulfur






32. 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.






33. Fuel for cars






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






35. Hard coal - with the second highest energy content






36. Soft coal - with the highest energy content






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






38. Heat - pressure - dearth of oxygen






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






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

41. A mixture of of hydrocarbons and organic compounds






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






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






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






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






46. 125000 Btu per gallon






47. 1 Therm = 100000 Btu






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






49. Fuel for trucks






50. 1 Btu = 2.931x10-4 kWh
