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. The layer of sediment where oil and gas originate.






2. Soft coal - with the highest energy content






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






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






5. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






8. Fuel for jets and tractors






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






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






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






12. Intermediate between hard coal and peat






13. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






16. Structural traps and stratigraphic traps






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






18. Oil with little or no sulfur






19. Hard coal - with the second highest energy content






20. Peat - formed from plants.






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






22. Fuel for cars






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






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






25. Energy






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

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






28. 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.






29. 1 Btu = 1055 J






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






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






32. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






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






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






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






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






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






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






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






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






43. 125000 Btu per gallon






44. Marine shale - limestone - or oil shale






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






46. A mixture of of hydrocarbons and organic compounds






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






48. 1 Therm = 100000 Btu






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






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