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






2. 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.






3. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






4. Fuel for trucks






5. Energy






6. 1 Btu = 1055 J






7. 1 Btu = 2.931x10-4 kWh






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






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






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






11. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






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






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






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






17. Heat - pressure - dearth of oxygen






18. 1 Therm = 100000 Btu






19. Oil with little or no sulfur






20. Marine shale - limestone - or oil shale






21. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






24. A mixture of of hydrocarbons and organic compounds






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






26. Traps formed by folding or faulting of rock layers






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






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






29. Soft coal - with the highest energy content






30. Peat - formed from plants.






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






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






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






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






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






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

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






38. For lubricating motors






39. Salt or cemented sandstone






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






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






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






43. Intermediate between hard coal and peat






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






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






46. Structural traps and stratigraphic traps






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






48. For heating - cooking - and making plastics






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






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