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






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






3. 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.






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






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






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






7. Hard coal - with the second highest energy content






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






9. For heating - cooking - and making plastics






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

11. For lubricating motors






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






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






14. Peat - formed from plants.






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






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






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






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






19. Fuel for trucks






20. Structural traps and stratigraphic traps






21. 1 Btu = 2.931x10-4 kWh






22. 1 Therm = 100000 Btu






23. Fuel for jets and tractors






24. Fuel for cars






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






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






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






28. Soot - sulfur oxides - nitrogen oxides - mercury






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






30. Energy






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






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






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






34. Soft coal - with the highest energy content






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






36. Oil with little or no sulfur






37. Marine shale - limestone - or oil shale






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






39. 125000 Btu per gallon






40. 22% of energy consumed in the U.S. comes from the burning of natural gas.






41. A mixture of of hydrocarbons and organic compounds






42. Salt or cemented sandstone






43. 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.






44. 1 Btu = 1055 J






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






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






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






48. Refined natural gas that contains pure methane.






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






50. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.
