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






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






3. Refined natural gas that contains pure methane.






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






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






6. Heat - pressure - dearth of oxygen






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






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






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






10. For lubricating motors






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

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






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






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






15. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






17. Fuel for trucks






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






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






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






21. Oil with little or no sulfur






22. Intermediate between hard coal and peat






23. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






26. Soft coal - with the highest energy content






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






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






29. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






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






33. A mixture of of hydrocarbons and organic compounds






34. Salt or cemented sandstone






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






36. Fuel for cars






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






38. Energy






39. 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.






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






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






42. Peat - formed from plants.






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






44. Marine shale - limestone - or oil shale






45. 1 Therm = 100000 Btu






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






47. Structural traps and stratigraphic traps






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






49. 1 Btu = 1055 J






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