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






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






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






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


5. Structural traps and stratigraphic traps






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






7. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






9. Heat - pressure - dearth of oxygen






10. Fuel for cars






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






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






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






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






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






16. Intermediate between hard coal and peat






17. A mixture of of hydrocarbons and organic compounds






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






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






20. 1 Btu = 1055 J






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






22. Refined natural gas that contains pure methane.






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






24. Fuel for trucks






25. Traps formed by folding or faulting of rock layers






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






27. Marine shale - limestone - or oil shale






28. 125000 Btu per gallon






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






30. For heating - cooking - and making plastics






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






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






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






34. Salt or cemented sandstone






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






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






37. Oil with little or no sulfur






38. Fuel for jets and tractors






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






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






41. Hard coal - with the second highest energy content






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






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






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






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






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






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






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






49. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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