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






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






4. 1 Btu = 2.931x10-4 kWh






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






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






7. 1 Btu = 1055 J






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






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






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






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






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






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






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






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






16. Salt or cemented sandstone






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






18. Fuel for cars






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






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

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






22. Heat - pressure - dearth of oxygen






23. Refined natural gas that contains pure methane.






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






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






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






27. Oil with little or no sulfur






28. 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.






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






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






31. Traps formed by folding or faulting of rock layers






32. Soft coal - with the highest energy content






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






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






35. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






37. Soot - sulfur oxides - nitrogen oxides - mercury






38. Structural traps and stratigraphic traps






39. 125000 Btu per gallon






40. For lubricating motors






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






42. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






43. Peat - formed from plants.






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






45. Hard coal - with the second highest energy content






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






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






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






49. Energy






50. Fuel for jets and tractors
