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






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






3. 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.






4. Heat - pressure - dearth of oxygen






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






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






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






8. Fuel for trucks






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






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






11. Refined natural gas that contains pure methane.






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






13. Fuel for jets and tractors






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






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






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






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






18. 1 Btu = 1055 J






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






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






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






22. Oil with little or no sulfur






23. Peat - formed from plants.






24. Structural traps and stratigraphic traps






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






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






27. Marine shale - limestone - or oil shale






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






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






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






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






32. For lubricating motors






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






34. Traps formed by folding or faulting of rock layers






35. Fuel for cars






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

37. 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.






38. 1 Btu = 2.931x10-4 kWh






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






40. 22% of energy consumed in the U.S. comes from the burning of natural gas.






41. For heating - cooking - and making plastics






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






43. Hard coal - with the second highest energy content






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






45. 125000 Btu per gallon






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






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






48. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






50. Soft coal - with the highest energy content
