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






2. A mixture of of hydrocarbons and organic compounds






3. Intermediate between hard coal and peat






4. For lubricating motors






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






6. 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.






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






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






9. Soft coal - with the highest energy content






10. Structural traps and stratigraphic traps






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






12. Energy






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






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






15. 1 Btu = 1055 J






16. Heat - pressure - dearth of oxygen






17. Marine shale - limestone - or oil shale






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






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






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






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






22. 125000 Btu per gallon






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






24. Peat - formed from plants.






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






26. 1 Btu = 2.931x10-4 kWh






27. Oil with little or no sulfur






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






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






30. Traps formed by folding or faulting of rock layers






31. Fuel for cars






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






33. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






34. Hard coal - with the second highest energy content






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






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






37. 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.






38. 1 Therm = 100000 Btu






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






40. Soot - sulfur oxides - nitrogen oxides - mercury






41. Fuel for jets and tractors






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






43. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






45. For heating - cooking - and making plastics






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






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






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






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






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