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. Oil with little or no sulfur






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






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






4. 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.






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






6. Fuel for cars






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






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






9. Soft coal - with the highest energy content






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






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






12. Salt or cemented sandstone






13. Fuel for trucks






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






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






16. Marine shale - limestone - or oil shale






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






18. For lubricating motors






19. Peat - formed from plants.






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






21. Heat - pressure - dearth of oxygen






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






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






24. Structural traps and stratigraphic traps






25. A mixture of of hydrocarbons and organic compounds






26. Traps formed by folding or faulting of rock layers






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






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

30. 1 Therm = 100000 Btu






31. Soot - sulfur oxides - nitrogen oxides - mercury






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






33. Refined natural gas that contains pure methane.






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






35. 1 Btu = 2.931x10-4 kWh






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






37. 125000 Btu per gallon






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






39. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






40. Fuel for jets and tractors






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






42. Intermediate between hard coal and peat






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






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






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






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






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






48. 22% of energy consumed in the U.S. comes from the burning of natural gas.






49. 1 Btu = 1055 J






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