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. 1 Btu = 2.931x10-4 kWh






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






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






4. 125000 Btu per gallon






5. Marine shale - limestone - or oil shale






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






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






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






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






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






11. Traps formed by folding or faulting of rock layers






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






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






14. 1 Therm = 100000 Btu






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






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






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






18. 1 Btu = 1055 J






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






20. Intermediate between hard coal and peat






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

22. Soft coal - with the highest energy content






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






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






25. A mixture of of hydrocarbons and organic compounds






26. Fuel for jets and tractors






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






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






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






30. 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.






31. Soot - sulfur oxides - nitrogen oxides - mercury






32. Fuel for cars






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






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






35. Fuel for trucks






36. Peat - formed from plants.






37. Refined natural gas that contains pure methane.






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






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






40. Heat - pressure - dearth of oxygen






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






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






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






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






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






46. Energy






47. Oil with little or no sulfur






48. For heating - cooking - and making plastics






49. Salt or cemented sandstone






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