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. Heat - pressure - dearth of oxygen






3. Intermediate between hard coal and peat






4. 1 Btu = 2.931x10-4 kWh






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






6. For heating - cooking - and making plastics






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






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






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






10. Soot - sulfur oxides - nitrogen oxides - mercury






11. Hard coal - with the second highest energy content






12. Energy






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






14. Fuel for cars






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






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






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






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. Fuel for jets and tractors






20. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






22. A mixture of of hydrocarbons and organic compounds






23. Peat - formed from plants.






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






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






26. Fuel for trucks






27. Salt or cemented sandstone






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






29. 1 Therm = 100000 Btu






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






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






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






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






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






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






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






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






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






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






40. Marine shale - limestone - or oil shale






41. 125000 Btu per gallon






42. Structural traps and stratigraphic traps






43. 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.






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






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






46. Soft coal - with the highest energy content






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






48. For lubricating motors






49. Traps formed by folding or faulting of rock layers






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