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






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






3. Heat - pressure - dearth of oxygen






4. For heating - cooking - and making plastics






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






6. Fuel for trucks






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






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


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






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






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






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






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






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






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






16. Intermediate between hard coal and peat






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






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






19. Hard coal - with the second highest energy content






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






21. 125000 Btu per gallon






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






23. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






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






27. Oil with little or no sulfur






28. 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.






29. Fuel for cars






30. Structural traps and stratigraphic traps






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






32. Refined natural gas that contains pure methane.






33. Energy






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






35. Marine shale - limestone - or oil shale






36. 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.






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






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






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






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






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






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






43. Soot - sulfur oxides - nitrogen oxides - mercury






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. Traps formed by folding or faulting of rock layers






47. Salt or cemented sandstone






48. Soft coal - with the highest energy content






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






50. 1 Therm = 100000 Btu
