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






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






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






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






5. 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.






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






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






8. Intermediate between hard coal and peat






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






10. Soft coal - with the highest energy content






11. Energy






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






13. A mixture of of hydrocarbons and organic compounds






14. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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

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






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






19. 125000 Btu per gallon






20. Structural traps and stratigraphic traps






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






22. For heating - cooking - and making plastics






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






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






25. Oil with little or no sulfur






26. 1 Btu = 1055 J






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






28. Refined natural gas that contains pure methane.






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






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






31. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






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. Heat - pressure - dearth of oxygen






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






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






39. 1 Btu = 2.931x10-4 kWh






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






41. 1 Therm = 100000 Btu






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






43. Traps formed by folding or faulting of rock layers






44. For lubricating motors






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






46. Marine shale - limestone - or oil shale






47. Peat - formed from plants.






48. Hard coal - with the second highest energy content






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






50. Fuel for jets and tractors
