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. Structural traps and stratigraphic traps






2. Fuel for jets and tractors






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






4. Salt or cemented sandstone






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






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






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






8. 1 Btu = 2.931x10-4 kWh






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






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

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






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






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






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






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






16. 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.






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






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






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






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






21. Marine shale - limestone - or oil shale






22. Hard coal - with the second highest energy content






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






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






25. Fuel for trucks






26. 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.






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






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






29. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






30. 1 Therm = 100000 Btu






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






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






33. A mixture of of hydrocarbons and organic compounds






34. Energy






35. Oil with little or no sulfur






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






37. Heat - pressure - dearth of oxygen






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






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






40. Soft coal - with the highest energy content






41. Traps formed by folding or faulting of rock layers






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






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






44. For heating - cooking - and making plastics






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






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






47. 1 Btu = 1055 J






48. Fuel for cars






49. 125000 Btu per gallon






50. Refined natural gas that contains pure methane.
