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. Traps formed by folding or faulting of rock layers






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






3. Soft coal - with the highest energy content






4. Structural traps and stratigraphic traps






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






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






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






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






10. Heat - pressure - dearth of oxygen






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






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






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






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

15. Fuel for cars






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






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






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






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






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






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






22. For heating - cooking - and making plastics






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






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






25. Marine shale - limestone - or oil shale






26. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






29. Peat - formed from plants.






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






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






32. Energy






33. 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.






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






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






36. Fuel for trucks






37. 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.






38. Salt or cemented sandstone






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






40. Intermediate between hard coal and peat






41. 1 Btu = 2.931x10-4 kWh






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






43. 1 Therm = 100000 Btu






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






45. A mixture of of hydrocarbons and organic compounds






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






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






48. 1 Btu = 1055 J






49. Fuel for jets and tractors






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