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






2. 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.






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






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






5. Oil with little or no sulfur






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






7. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






9. Soft coal - with the highest energy content






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






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






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






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






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






15. Energy






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






17. Intermediate between hard coal and peat






18. Structural traps and stratigraphic traps






19. Hard coal - with the second highest energy content






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






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






22. 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.






23. 1 Therm = 100000 Btu






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






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






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






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






28. Peat - formed from plants.






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






30. 1 Btu = 1055 J






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






32. For lubricating motors






33. Fuel for cars






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






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






36. Salt or cemented sandstone






37. 1 Btu = 2.931x10-4 kWh






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






39. Refined natural gas that contains pure methane.






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






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






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






43. For heating - cooking - and making plastics






44. Soot - sulfur oxides - nitrogen oxides - mercury






45. Traps formed by folding or faulting of rock layers






46. Marine shale - limestone - or oil shale






47. A mixture of of hydrocarbons and organic compounds






48. Fuel for jets and tractors






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






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