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






3. Soot - sulfur oxides - nitrogen oxides - mercury






4. 1 Therm = 100000 Btu






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






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






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






8. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






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






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






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






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






15. 125000 Btu per gallon






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






17. A mixture of of hydrocarbons and organic compounds






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






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






20. 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.






21. Soft coal - with the highest energy content






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

23. Traps formed by folding or faulting of rock layers






24. Hard coal - with the second highest energy content






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






26. Peat - formed from plants.






27. 1 Btu = 2.931x10-4 kWh






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






29. Heat - pressure - dearth of oxygen






30. Fuel for jets and tractors






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






32. For lubricating motors






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






34. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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. Salt or cemented sandstone






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






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






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






41. Fuel for trucks






42. Structural traps and stratigraphic traps






43. 1 Btu = 1055 J






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






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






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






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






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






49. Fuel for cars






50. Intermediate between hard coal and peat
