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






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






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






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






5. Fuel for jets and tractors






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






7. Refined natural gas that contains pure methane.






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






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






10. Traps formed by folding or faulting of rock layers






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






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






13. Energy






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






15. Peat - formed from plants.






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






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






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






19. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






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. For heating - cooking - and making plastics






24. 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.






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






26. 1 Btu = 2.931x10-4 kWh






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

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






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






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






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






32. Hard coal - with the second highest energy content






33. 125000 Btu per gallon






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






35. Salt or cemented sandstone






36. Heat - pressure - dearth of oxygen






37. Marine shale - limestone - or oil shale






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






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






40. Soft coal - with the highest energy content






41. Fuel for cars






42. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






45. 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.






46. 22% of energy consumed in the U.S. comes from the burning of natural gas.






47. A mixture of of hydrocarbons and organic compounds






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






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






50. For lubricating motors
