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. Fuel for trucks






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






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






4. Traps formed by folding or faulting of rock layers






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






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






7. Oil with little or no sulfur






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






9. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






12. 1 Therm = 100000 Btu






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






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






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






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






17. Fuel for cars






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






19. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






22. For heating - cooking - and making plastics






23. Refined natural gas that contains pure methane.






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






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






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






27. Salt or cemented sandstone






28. 125000 Btu per gallon






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






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






31. 1 Btu = 1055 J






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






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






34. 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.






35. Soft coal - with the highest energy content






36. Heat - pressure - dearth of oxygen






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






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

39. Fuel for jets and tractors






40. Marine shale - limestone - or oil shale






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






42. Structural traps and stratigraphic traps






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






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






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






46. A mixture of of hydrocarbons and organic compounds






47. For lubricating motors






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






49. Hard coal - with the second highest energy content






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