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






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






4. 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.






5. 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.






6. Structural traps and stratigraphic traps






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






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






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






10. 125000 Btu per gallon






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






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






13. 1 Btu = 1055 J






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






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






16. Peat - formed from plants.






17. Hard coal - with the second highest energy content






18. For lubricating motors






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






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






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






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






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






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






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






26. A mixture of of hydrocarbons and organic compounds






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






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






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






30. Fuel for trucks






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






32. 1 Btu = 2.931x10-4 kWh






33. 22% of energy consumed in the U.S. comes from the burning of natural gas.






34. Soot - sulfur oxides - nitrogen oxides - mercury






35. Refined natural gas that contains pure methane.






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






37. Heat - pressure - dearth of oxygen






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






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






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






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






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






43. Energy






44. For heating - cooking - and making plastics






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






46. Soft coal - with the highest energy content






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






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






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






50. Oil with little or no sulfur
