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






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






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






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






5. Intermediate between hard coal and peat






6. Oil with little or no sulfur






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






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






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






10. Fuel for cars






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






12. Marine shale - limestone - or oil shale






13. Heat - pressure - dearth of oxygen






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






15. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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. Refined natural gas that contains pure methane.






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






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






20. 1 Therm = 100000 Btu






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






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






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






24. 1 Btu = 1055 J






25. Structural traps and stratigraphic traps






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






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






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






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






30. A mixture of of hydrocarbons and organic compounds






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






32. For heating - cooking - and making plastics






33. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






34. Energy






35. 1 Btu = 2.931x10-4 kWh






36. Fuel for jets and tractors






37. 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.






38. Peat - formed from plants.






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






40. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






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






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






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






46. Fuel for trucks






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






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






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






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