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. A mixture of hydrocarbons found in naturally occurring underground reservoirs






2. Hard coal - with the second highest energy content






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






4. 1 Therm = 100000 Btu






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






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






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






8. Intermediate between hard coal and peat






9. Fuel for trucks






10. 1 Btu = 1055 J






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






12. 125000 Btu per gallon






13. Salt or cemented sandstone






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






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






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






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






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






19. For heating - cooking - and making plastics






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






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






22. Soot - sulfur oxides - nitrogen oxides - mercury






23. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






25. Oil with little or no sulfur






26. For lubricating motors






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






28. Structural traps and stratigraphic traps






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






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






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






32. Fuel for jets and tractors






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






34. Traps formed by folding or faulting of rock layers






35. 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.






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






37. Fuel for cars






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


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






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






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






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. Soft coal - with the highest energy content






44. Marine shale - limestone - or oil shale






45. Energy






46. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






49. 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.






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