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. Energy






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






3. 1 Btu = 2.931x10-4 kWh






4. Fuel for trucks






5. Structural traps and stratigraphic traps






6. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






7. Soot - sulfur oxides - nitrogen oxides - mercury






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






9. Salt or cemented sandstone






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






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






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






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

14. Hard coal - with the second highest energy content






15. For heating - cooking - and making plastics






16. Traps formed by folding or faulting of rock layers






17. Fuel for cars






18. Peat - formed from plants.






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






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






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






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






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






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






25. Marine shale - limestone - or oil shale






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






27. Intermediate between hard coal and peat






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






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






30. For lubricating motors






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






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






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






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






35. 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.






36. 1 Therm = 100000 Btu






37. Oil with little or no sulfur






38. 1 Btu = 1055 J






39. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






42. Soft coal - with the highest energy content






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






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






45. Fuel for jets and tractors






46. 125000 Btu per gallon






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






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






49. 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.






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