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






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






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

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






5. Refined natural gas that contains pure methane.






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






7. Salt or cemented sandstone






8. Heat - pressure - dearth of oxygen






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






10. 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.






11. Intermediate between hard coal and peat






12. Peat - formed from plants.






13. Energy






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






15. Marine shale - limestone - or oil shale






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






17. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






19. Hard coal - with the second highest energy content






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






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






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






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






24. Traps formed by folding or faulting of rock layers






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






26. Structural traps and stratigraphic traps






27. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






30. A mixture of of hydrocarbons and organic compounds






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






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






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






34. For lubricating motors






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






36. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






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






40. 1 Btu = 2.931x10-4 kWh






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






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






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






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






45. Fuel for trucks






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






47. Soft coal - with the highest energy content






48. For heating - cooking - and making plastics






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






50. 125000 Btu per gallon
