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 layer of sediment where oil and gas originate.






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






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

4. Intermediate between hard coal and peat






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






6. 1 Btu = 1055 J






7. 1 Therm = 100000 Btu






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






9. For heating - cooking - and making plastics






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






11. 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.






12. 125000 Btu per gallon






13. A mixture of of hydrocarbons and organic compounds






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






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






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






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






18. For lubricating motors






19. Soft coal - with the highest energy content






20. Energy






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






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






23. Fuel for jets and tractors






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






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






26. Hard coal - with the second highest energy content






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






28. Marine shale - limestone - or oil shale






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






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






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






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






33. Salt or cemented sandstone






34. Heat - pressure - dearth of oxygen






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






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






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






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






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






40. 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.






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






42. Structural traps and stratigraphic traps






43. Peat - formed from plants.






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






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






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






47. Soot - sulfur oxides - nitrogen oxides - mercury






48. Fuel for cars






49. 1 Btu = 2.931x10-4 kWh






50. Fuel for trucks
