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






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






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






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






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






6. Hard coal - with the second highest energy content






7. Refined natural gas that contains pure methane.






8. 125000 Btu per gallon






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






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






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






12. 22% of energy consumed in the U.S. comes from the burning of natural gas.






13. Traps formed by folding or faulting of rock layers






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






15. 1 Btu = 1055 J






16. Peat - formed from plants.






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






18. Structural traps and stratigraphic traps






19. For heating - cooking - and making plastics






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

21. Salt or cemented sandstone






22. For lubricating motors






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






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






25. A mixture of of hydrocarbons and organic compounds






26. Heat - pressure - dearth of oxygen






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






28. Marine shale - limestone - or oil shale






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






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






31. Oil with little or no sulfur






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






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






34. 1 Btu = 2.931x10-4 kWh






35. Intermediate between hard coal and peat






36. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






37. Fuel for trucks






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






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






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






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






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






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






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






45. 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.






46. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






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






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