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






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






4. Soft coal - with the highest energy content






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






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






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






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






9. Peat - formed from plants.






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






11. A mixture of of hydrocarbons and organic compounds






12. 1 Therm = 100000 Btu






13. 22% of energy consumed in the U.S. comes from the burning of natural gas.






14. For lubricating motors






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






16. Marine shale - limestone - or oil shale






17. 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.






18. Salt or cemented sandstone






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






20. Oil with little or no sulfur






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






22. Refined natural gas that contains pure methane.






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






24. 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.






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






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






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






28. Heat - pressure - dearth of oxygen






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






30. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






31. Fuel for cars






32. Hard coal - with the second highest energy content






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






34. 1 Btu = 2.931x10-4 kWh






35. 1 Btu = 1055 J






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






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






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






39. 125000 Btu per gallon






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






41. Fuel for jets and tractors






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






43. For heating - cooking - and making plastics






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






45. Soot - sulfur oxides - nitrogen oxides - mercury






46. Fuel for trucks






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






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






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






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