CSET Earth Resources Fossil Fuels

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. The layer of sediment where oil and gas originate.






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






4. Intermediate between hard coal and peat






5. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






7. For lubricating motors






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






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






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






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






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






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






14. 1 Therm = 100000 Btu






15. Salt or cemented sandstone






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






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






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






19. Fuel for trucks






20. Structural traps and stratigraphic traps






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






22. Soot - sulfur oxides - nitrogen oxides - mercury






23. Oil with little or no sulfur






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






25. Refined natural gas that contains pure methane.






26. Heat - pressure - dearth of oxygen






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






28. For heating - cooking - and making plastics






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






30. Soft coal - with the highest energy content






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






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






33. Peat - formed from plants.






34. 1 Btu = 1055 J






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






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






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






38. A mixture of of hydrocarbons and organic compounds






39. 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.






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






41. Energy






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






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






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

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






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






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






48. Fuel for cars






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






50. Hard coal - with the second highest energy content
