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






2. Peat - formed from plants.






3. Traps formed by folding or faulting of rock layers






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






5. 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.






6. Structural traps and stratigraphic traps






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






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






9. Marine shale - limestone - or oil shale






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






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






12. 1 Therm = 100000 Btu






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






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






15. 22% of energy consumed in the U.S. comes from the burning of natural gas.






16. Fuel for cars






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






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






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


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






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






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






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






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






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






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. Energy






28. Heat - pressure - dearth of oxygen






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






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






31. Salt or cemented sandstone






32. Soft coal - with the highest energy content






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






34. Fuel for jets and tractors






35. Intermediate between hard coal and peat






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






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






38. Refined natural gas that contains pure methane.






39. Hard coal - with the second highest energy content






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






41. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






42. For lubricating motors






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






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






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






46. Oil with little or no sulfur






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






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






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






50. 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.
