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


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






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






4. 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.






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






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






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






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






9. Refined natural gas that contains pure methane.






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






11. 22% of energy consumed in the U.S. comes from the burning of natural gas.






12. For lubricating motors






13. 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.






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






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






16. A mixture of of hydrocarbons and organic compounds






17. 125000 Btu per gallon






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






19. Structural traps and stratigraphic traps






20. Soot - sulfur oxides - nitrogen oxides - mercury






21. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






23. Energy






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






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






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






27. Hard coal - with the second highest energy content






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






29. 1 Btu = 1055 J






30. 1 Btu = 2.931x10-4 kWh






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






32. Fuel for trucks






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






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






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






36. Heat - pressure - dearth of oxygen






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






38. Fuel for jets and tractors






39. Marine shale - limestone - or oil shale






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






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






42. Fuel for cars






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






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






45. Intermediate between hard coal and peat






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






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






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






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






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