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 ratio of the energy return to the energy invested.






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






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






4. Intermediate between hard coal and peat






5. 22% of energy consumed in the U.S. comes from the burning of natural gas.






6. Fuel for cars






7. For heating - cooking - and making plastics






8. Traps formed by folding or faulting of rock layers






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






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






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






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






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






14. Structural traps and stratigraphic traps






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






16. A mixture of of hydrocarbons and organic compounds






17. Soot - sulfur oxides - nitrogen oxides - mercury






18. Heat - pressure - dearth of oxygen






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






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






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






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






23. Fuel for jets and tractors






24. Hard coal - with the second highest energy content






25. Oil with little or no sulfur






26. Salt or cemented sandstone






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






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






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






30. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






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






34. 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.






35. Energy






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






37. For lubricating motors






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






39. 1 Therm = 100000 Btu






40. 125000 Btu per gallon






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






42. 1 Btu = 1055 J






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






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






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






46. 1 Btu = 2.931x10-4 kWh






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






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






49. Refined natural gas that contains pure methane.






50. Fuel for trucks
