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






2. 1 Therm = 100000 Btu






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






4. 125000 Btu per gallon






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






6. Intermediate between hard coal and peat






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






8. 22% of energy consumed in the U.S. comes from the burning of natural gas.






9. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






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






13. Traps formed by folding or faulting of rock layers






14. Soft coal - with the highest energy content






15. A mixture of of hydrocarbons and organic compounds






16. Structural traps and stratigraphic traps






17. 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.






18. 1 Btu = 1055 J






19. Energy






20. For heating - cooking - and making plastics






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






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






23. For lubricating motors






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






25. 1 Btu = 2.931x10-4 kWh






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






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






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






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






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






31. Refined natural gas that contains pure methane.






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






33. Marine shale - limestone - or oil shale






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






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






36. Hard coal - with the second highest energy content






37. Fuel for jets and tractors






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






39. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






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






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






44. Fuel for trucks






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






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






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

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






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






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