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. Intermediate between hard coal and peat






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






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






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






5. 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.






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






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






8. Salt or cemented sandstone






9. 1 Btu = 1055 J






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






11. Hard coal - with the second highest energy content






12. 1 Btu = 2.931x10-4 kWh






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






14. Oil with little or no sulfur






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






16. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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

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






19. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






21. Fuel for jets and tractors






22. For heating - cooking - and making plastics






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






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






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






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






27. 1 Therm = 100000 Btu






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






29. Traps formed by folding or faulting of rock layers






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






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






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






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






34. Refined natural gas that contains pure methane.






35. Heat - pressure - dearth of oxygen






36. 125000 Btu per gallon






37. A mixture of of hydrocarbons and organic compounds






38. Structural traps and stratigraphic traps






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






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






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






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






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






44. Fuel for cars






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






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






47. Fuel for trucks






48. Peat - formed from plants.






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






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