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






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






3. Intermediate between hard coal and peat






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






5. Peat - formed from plants.






6. Energy






7. Structural traps and stratigraphic traps






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






9. For heating - cooking - and making plastics






10. 1 Therm = 100000 Btu






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






12. Oil with little or no sulfur






13. Soft coal - with the highest energy content






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






15. Refined natural gas that contains pure methane.






16. Heat - pressure - dearth of oxygen






17. 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.






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






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






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






21. Salt or cemented sandstone






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






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






24. A mixture of of hydrocarbons and organic compounds






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






26. Marine shale - limestone - or oil shale






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

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






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






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






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






32. 22% of energy consumed in the U.S. comes from the burning of natural gas.






33. Fuel for trucks






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






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






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






37. 1 Btu = 1055 J






38. For lubricating motors






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






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






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






42. Fuel for jets and tractors






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






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






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






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






47. Fuel for cars






48. 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.






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






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