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






3. Hard coal - with the second highest energy content






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






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






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






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






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






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






10. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






12. 125000 Btu per gallon






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






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






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






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






17. Peat - formed from plants.






18. For lubricating motors






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






20. Traps formed by folding or faulting of rock layers






21. 1 Therm = 100000 Btu






22. Refined natural gas that contains pure methane.






23. Soot - sulfur oxides - nitrogen oxides - mercury






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






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

26. Marine shale - limestone - or oil shale






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






28. 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.






29. Salt or cemented sandstone






30. For heating - cooking - and making plastics






31. Oil with little or no sulfur






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






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






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






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






36. Fuel for trucks






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






38. Energy






39. 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.






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






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






42. Fuel for jets and tractors






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






44. A mixture of of hydrocarbons and organic compounds






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






46. Soft coal - with the highest energy content






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






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






49. Structural traps and stratigraphic traps






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