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. Intermediate between hard coal and peat






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

3. Heat - pressure - dearth of oxygen






4. 1 Therm = 100000 Btu






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






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






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






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






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






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






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






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






13. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






14. Peat - formed from plants.






15. Hard coal - with the second highest energy content






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






17. Fuel for jets and tractors






18. 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.






19. 125000 Btu per gallon






20. Fuel for trucks






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






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






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






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






25. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






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






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






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






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






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






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






34. Soot - sulfur oxides - nitrogen oxides - mercury






35. 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.






36. Structural traps and stratigraphic traps






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






38. 1 Btu = 1055 J






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






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






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






42. For heating - cooking - and making plastics






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






44. Fuel for cars






45. Traps formed by folding or faulting of rock layers






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






47. Salt or cemented sandstone






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






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






50. A mixture of of hydrocarbons and organic compounds
