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. For lubricating motors






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






4. Hard coal - with the second highest energy content






5. Soot - sulfur oxides - nitrogen oxides - mercury






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






7. 1 Btu = 1055 J






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






9. A mixture of of hydrocarbons and organic compounds






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






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






12. Salt or cemented sandstone






13. Structural traps and stratigraphic traps






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






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






16. Soft coal - with the highest energy content






17. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






19. Marine shale - limestone - or oil shale






20. Heat - pressure - dearth of oxygen






21. 125000 Btu per gallon






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






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






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






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






26. 1 Btu = 2.931x10-4 kWh






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






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






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






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






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






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






33. Oil with little or no sulfur






34. 1 Therm = 100000 Btu






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






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






37. Fuel for cars






38. Intermediate between hard coal and peat






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






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






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






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






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






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






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






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






47. 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.






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






49. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






50. Peat - formed from plants.
