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






2. Soft coal - with the highest energy content






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






4. Refined natural gas that contains pure methane.






5. 1 Btu = 1055 J






6. 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.






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






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






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






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






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






12. Fuel for jets and tractors






13. 125000 Btu per gallon






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






15. A mixture of of hydrocarbons and organic compounds






16. 1 Btu = 2.931x10-4 kWh






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






18. Soot - sulfur oxides - nitrogen oxides - mercury






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






20. Salt or cemented sandstone






21. Marine shale - limestone - or oil shale






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






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






24. Energy






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






26. Fuel for trucks






27. Structural traps and stratigraphic traps






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






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






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






31. Oil with little or no sulfur






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






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






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






35. Fuel for cars






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






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






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






39. 22% of energy consumed in the U.S. comes from the burning of natural gas.






40. Intermediate between hard coal and peat






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






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






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






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

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






46. Hard coal - with the second highest energy content






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






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






49. Heat - pressure - dearth of oxygen






50. 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.
