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. Energy






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






3. Intermediate between hard coal and peat






4. Hard coal - with the second highest energy content






5. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






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






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






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






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






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






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






14. Salt or cemented sandstone






15. Oil with little or no sulfur






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






17. For heating - cooking - and making plastics






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






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






20. 1 Therm = 100000 Btu






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






22. Heat - pressure - dearth of oxygen






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






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






25. For lubricating motors






26. Fuel for trucks






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






28. Marine shale - limestone - or oil shale






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






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






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






32. Fuel for cars






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






34. Soot - sulfur oxides - nitrogen oxides - mercury






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






36. 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.






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

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






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






40. Peat - formed from plants.






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






42. 1 Btu = 2.931x10-4 kWh






43. 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.






44. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






46. 125000 Btu per gallon






47. 1 Btu = 1055 J






48. A mixture of of hydrocarbons and organic compounds






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






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