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 ratio of the energy return to the energy invested.






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






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






4. Intermediate between hard coal and peat






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






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






7. For lubricating motors






8. Fuel for cars






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






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






11. A mixture of of hydrocarbons and organic compounds






12. Peat - formed from plants.






13. Hard coal - with the second highest energy content






14. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






17. Salt or cemented sandstone






18. 1 Btu = 2.931x10-4 kWh






19. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






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






23. Heat - pressure - dearth of oxygen






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






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






26. Marine shale - limestone - or oil shale






27. 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.






28. Energy






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






30. 22% of energy consumed in the U.S. comes from the burning of natural gas.






31. For heating - cooking - and making plastics






32. 1 Btu = 1055 J






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






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






35. Traps formed by folding or faulting of rock layers






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






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






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






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






40. 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.






41. 125000 Btu per gallon






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






43. Refined natural gas that contains pure methane.






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






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






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






47. Fuel for trucks






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






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






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