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






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






3. Intermediate between hard coal and peat






4. Oil with little or no sulfur






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






6. Salt or cemented sandstone






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






8. 1 Btu = 1055 J






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






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






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






12. Hard coal - with the second highest energy content






13. 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.






14. For heating - cooking - and making plastics






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






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






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






18. Marine shale - limestone - or oil shale






19. Energy






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






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






22. Fuel for trucks






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






24. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






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






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






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

30. For lubricating motors






31. 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.






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






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






34. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






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






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






39. 1 Btu = 2.931x10-4 kWh






40. 125000 Btu per gallon






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






42. Fuel for cars






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






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






45. Refined natural gas that contains pure methane.






46. Heat - pressure - dearth of oxygen






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






48. Fuel for jets and tractors






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






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