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






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






3. For lubricating motors






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






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

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






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






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






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






10. 125000 Btu per gallon






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






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






13. Structural traps and stratigraphic traps






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






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






16. Peat - formed from plants.






17. Fuel for trucks






18. 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.






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






20. 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.






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






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






23. Oil with little or no sulfur






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






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






26. Soot - sulfur oxides - nitrogen oxides - mercury






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






28. Marine shale - limestone - or oil shale






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






30. 22% of energy consumed in the U.S. comes from the burning of natural gas.






31. 1 Therm = 100000 Btu






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






33. Refined natural gas that contains pure methane.






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






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






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






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






38. Salt or cemented sandstone






39. A mixture of of hydrocarbons and organic compounds






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






41. Fuel for cars






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






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






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






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






46. 1 Btu = 1055 J






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






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






49. Soft coal - with the highest energy content






50. Energy
