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






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






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






4. Oil with little or no sulfur






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






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






7. 125000 Btu per gallon






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






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






10. Peat - formed from plants.






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






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






13. For lubricating motors






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






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






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






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






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






19. 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.






20. Structural traps and stratigraphic traps






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






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






23. Soot - sulfur oxides - nitrogen oxides - mercury






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






25. Refined natural gas that contains pure methane.






26. Salt or cemented sandstone






27. Energy






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






29. Hard coal - with the second highest energy content






30. 1 Btu = 1055 J






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






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






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






34. Intermediate between hard coal and peat






35. Soft coal - with the highest energy content






36. Marine shale - limestone - or oil shale






37. Fuel for cars






38. 1 Therm = 100000 Btu






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






40. Fuel for jets and tractors






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






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






43. Traps formed by folding or faulting of rock layers






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






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






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






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






48. Fuel for trucks






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






50. Heat - pressure - dearth of oxygen
