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






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






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






4. Hard coal - with the second highest energy content






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


6. Fuel for jets and tractors






7. Traps formed by folding or faulting of rock layers






8. Peat - formed from plants.






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






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






11. Energy






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






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






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






15. 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.






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






17. 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.






18. 1 Btu = 1055 J






19. Heat - pressure - dearth of oxygen






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






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






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






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






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






25. Structural traps and stratigraphic traps






26. Fuel for trucks






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






28. A mixture of of hydrocarbons and organic compounds






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






30. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






32. Soft coal - with the highest energy content






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






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






35. 22% of energy consumed in the U.S. comes from the burning of natural gas.






36. Fuel for cars






37. 125000 Btu per gallon






38. Soot - sulfur oxides - nitrogen oxides - mercury






39. Oil with little or no sulfur






40. 1 Therm = 100000 Btu






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






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






43. For lubricating motors






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






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






46. Refined natural gas that contains pure methane.






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






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






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






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