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. Fuel for trucks






2. 1 Btu = 1055 J






3. Soot - sulfur oxides - nitrogen oxides - mercury






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

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






6. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






9. Salt or cemented sandstone






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






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






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






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






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






15. For heating - cooking - and making plastics






16. Traps formed by folding or faulting of rock layers






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






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






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. Refined natural gas that contains pure methane.






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






22. Intermediate between hard coal and peat






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






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






25. Fuel for jets and tractors






26. Soft coal - with the highest energy content






27. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






29. Structural traps and stratigraphic traps






30. Energy






31. 1 Btu = 2.931x10-4 kWh






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






33. Oil with little or no sulfur






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






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






36. 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.






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






38. 1 Therm = 100000 Btu






39. A mixture of of hydrocarbons and organic compounds






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






41. Fuel for cars






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






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






44. 125000 Btu per gallon






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






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






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






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






49. 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.






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