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. Peat - formed from plants.






2. Energy






3. Intermediate between hard coal and peat






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






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






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






7. Heat - pressure - dearth of oxygen






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






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






10. Fuel for cars






11. Fuel for jets and tractors






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






13. Soft coal - with the highest energy content






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

15. 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.






16. 1 Btu = 2.931x10-4 kWh






17. Structural traps and stratigraphic traps






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






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






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






21. Marine shale - limestone - or oil shale






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






23. 125000 Btu per gallon






24. Refined natural gas that contains pure methane.






25. 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.






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






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






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






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






30. Hard coal - with the second highest energy content






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






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






33. Traps formed by folding or faulting of rock layers






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






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






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






37. 1 Btu = 1055 J






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






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






40. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






41. 1 Therm = 100000 Btu






42. Salt or cemented sandstone






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






44. A mixture of of hydrocarbons and organic compounds






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






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






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






48. Fuel for trucks






49. Soot - sulfur oxides - nitrogen oxides - mercury






50. Oil with little or no sulfur
