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. For lubricating motors






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






3. Energy






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






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






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






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






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






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






10. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






11. For heating - cooking - and making plastics






12. Heat - pressure - dearth of oxygen






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






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






15. 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.






16. 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.






17. Fuel for trucks






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






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

20. 125000 Btu per gallon






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






22. Refined natural gas that contains pure methane.






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






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






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






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






27. Soft coal - with the highest energy content






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






29. Marine shale - limestone - or oil shale






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






31. 1 Btu = 2.931x10-4 kWh






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






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






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






35. Intermediate between hard coal and peat






36. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






38. 1 Btu = 1055 J






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






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






41. Peat - formed from plants.






42. Hard coal - with the second highest energy content






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






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






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






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






47. A mixture of of hydrocarbons and organic compounds






48. Traps formed by folding or faulting of rock layers






49. Soot - sulfur oxides - nitrogen oxides - mercury






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