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. Hard coal - with the second highest energy content






2. Marine shale - limestone - or oil shale






3. 1 Btu = 2.931x10-4 kWh






4. 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.






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






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






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






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






9. Oil with little or no sulfur






10. Peat - formed from plants.






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






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






13. Fuel for jets and tractors






14. 1 Btu = 1055 J






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






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






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






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






19. Fuel for cars






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






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






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






23. Fuel for trucks






24. Intermediate between hard coal and peat






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






26. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






28. Refined natural gas that contains pure methane.






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






30. Structural traps and stratigraphic traps






31. For heating - cooking - and making plastics






32. Heat - pressure - dearth of oxygen






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






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






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






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






37. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






38. A mixture of of hydrocarbons and organic compounds






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






40. For lubricating motors






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






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






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






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






45. Energy






46. 1 Therm = 100000 Btu






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






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






49. Traps formed by folding or faulting of rock layers






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