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. Oil with little or no sulfur






3. For heating - cooking - and making plastics






4. Hard coal - with the second highest energy content






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






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






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






8. 1 Therm = 100000 Btu






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






10. 125000 Btu per gallon






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






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






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

14. Intermediate between hard coal and peat






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






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






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






18. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






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






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






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






24. Soft coal - with the highest energy content






25. 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.






26. 1 Btu = 2.931x10-4 kWh






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






28. Soot - sulfur oxides - nitrogen oxides - mercury






29. Traps formed by folding or faulting of rock layers






30. 22% of energy consumed in the U.S. comes from the burning of natural gas.






31. Fuel for jets and tractors






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






33. For lubricating motors






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






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






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






37. 1 Btu = 1055 J






38. Salt or cemented sandstone






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






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






41. Formed by changes in rock type or sedimentary features that create a space where hydrocarbons are confined by impermeable layers






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






43. Fuel for cars






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






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






46. A mixture of of hydrocarbons and organic compounds






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






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






49. Fuel for trucks






50. Refined natural gas that contains pure methane.
