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. Fuel for jets and tractors






2. Refined natural gas that contains pure methane.






3. Intermediate between hard coal and peat






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






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






6. A mixture of of hydrocarbons and organic compounds






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






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






9. 125000 Btu per gallon






10. Soft coal - with the highest energy content






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






12. Energy






13. 1 Btu = 2.931x10-4 kWh






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






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






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






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






18. Heat - pressure - dearth of oxygen






19. Fuel for trucks






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






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






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






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






24. For heating - cooking - and making plastics






25. Structural traps and stratigraphic traps






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






27. 1 Therm = 100000 Btu






28. Salt or cemented sandstone






29. Peat - formed from plants.






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






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






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






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






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






35. 1 Btu = 1055 J






36. For lubricating motors






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






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






39. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






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






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






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






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






46. Fuel for cars






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


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






49. Hard coal - with the second highest energy content






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