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






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






3. Soft coal - with the highest energy content






4. For lubricating motors






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






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






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






8. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






9. For heating - cooking - and making plastics






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






11. Salt or cemented sandstone






12. Oil with little or no sulfur






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






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






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






16. 22% of energy consumed in the U.S. comes from the burning of natural gas.






17. Marine shale - limestone - or oil shale






18. Peat - formed from plants.






19. Hard coal - with the second highest energy content






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






21. Energy






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






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






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






25. Intermediate between hard coal and peat






26. A mixture of of hydrocarbons and organic compounds






27. Fuel for jets and tractors






28. Refined natural gas that contains pure methane.






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






30. Fuel for cars






31. Structural traps and stratigraphic traps






32. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






35. 1 Btu = 2.931x10-4 kWh






36. 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.






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






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






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






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






41. 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.






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






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






44. Traps formed by folding or faulting of rock layers






45. 125000 Btu per gallon






46. Heat - pressure - dearth of oxygen






47. Fuel for trucks






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






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






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