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. Fuel for trucks






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






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






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






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






6. A mixture of of hydrocarbons and organic compounds






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






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






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






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






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






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






13. 22% of energy consumed in the U.S. comes from the burning of natural gas.






14. Peat - formed from plants.






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






16. For lubricating motors






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






18. Salt or cemented sandstone






19. Traps formed by folding or faulting of rock layers






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






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






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






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






24. Soot - sulfur oxides - nitrogen oxides - mercury






25. 1 Btu = 2.931x10-4 kWh






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






27. 1 Btu = 1055 J






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






29. Fuel for jets and tractors






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






31. For heating - cooking - and making plastics






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






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






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






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






36. Energy






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. Oil with little or no sulfur






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






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






41. Structural traps and stratigraphic traps






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






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






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






45. 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.






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






47. 125000 Btu per gallon






48. Intermediate between hard coal and peat






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






50. 1 Therm = 100000 Btu
