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. Salt or cemented sandstone






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






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






4. Refined natural gas that contains pure methane.






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






6. Intermediate between hard coal and peat






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






8. For heating - cooking - and making plastics






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






10. 1 Btu = 1055 J






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






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






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






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






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






16. Structural traps and stratigraphic traps






17. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






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






21. Oil with little or no sulfur






22. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






23. 1 Therm = 100000 Btu






24. Soft coal - with the highest energy content






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






26. Hard coal - with the second highest energy content






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






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






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


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






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






32. Fuel for trucks






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






34. Heat - pressure - dearth of oxygen






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






36. For lubricating motors






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






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






39. Fuel for jets and tractors






40. Peat - formed from plants.






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






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






43. Energy






44. Fuel for cars






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






46. 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.






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






48. 1 Btu = 2.931x10-4 kWh






49. 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.






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