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






2. Hard coal - with the second highest energy content






3. Soot - sulfur oxides - nitrogen oxides - mercury






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






5. Intermediate between hard coal and peat






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






7. For lubricating motors






8. 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.






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






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






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






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






13. Heat - pressure - dearth of oxygen






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






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






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






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






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






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






20. Marine shale - limestone - or oil shale






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






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






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






24. A mixture of of hydrocarbons and organic compounds






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






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






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






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






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






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






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






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






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






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






35. Structural traps and stratigraphic traps






36. Fuel for trucks






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






38. For heating - cooking - and making plastics






39. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






40. Traps formed by folding or faulting of rock layers






41. 1 Btu = 2.931x10-4 kWh






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






43. 1 Therm = 100000 Btu






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






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






46. Soft coal - with the highest energy content






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






48. Oil with little or no sulfur






49. Energy






50. Peat - formed from plants.
