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






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






3. 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.






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






5. Soft coal - with the highest energy content






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






7. 1 Btu = 2.931x10-4 kWh






8. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






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






12. Salt or cemented sandstone






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






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






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






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






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






18. Marine shale - limestone - or oil shale






19. Energy






20. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






23. 1 Therm = 100000 Btu






24. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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

26. Fuel for jets and tractors






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






28. 1 Btu = 1055 J






29. A mixture of of hydrocarbons and organic compounds






30. Heat - pressure - dearth of oxygen






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






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






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






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






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






36. Refined natural gas that contains pure methane.






37. Fuel for cars






38. Peat - formed from plants.






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






40. Structural traps and stratigraphic traps






41. For heating - cooking - and making plastics






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






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






44. Hard coal - with the second highest energy content






45. 125000 Btu per gallon






46. For lubricating motors






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






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






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






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