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






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






4. Salt or cemented sandstone






5. Fuel for trucks






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






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






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






9. Refined natural gas that contains pure methane.






10. Fuel for cars






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






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






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






14. Structural traps and stratigraphic traps






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






16. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






18. Marine shale - limestone - or oil shale






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






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






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






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






23. Heat - pressure - dearth of oxygen






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






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






26. 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.






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

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






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






30. Soot - sulfur oxides - nitrogen oxides - mercury






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






32. For heating - cooking - and making plastics






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






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






35. For lubricating motors






36. Hard coal - with the second highest energy content






37. Oil with little or no sulfur






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






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






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






41. Traps formed by folding or faulting of rock layers






42. 1 Therm = 100000 Btu






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






44. A mixture of of hydrocarbons and organic compounds






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






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






47. Fuel for jets and tractors






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






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






50. 1 Btu = 1055 J
