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 trucks






2. A mixture of of hydrocarbons and organic compounds






3. 1 Btu = 1055 J






4. Oil with little or no sulfur






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






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






7. Structural traps and stratigraphic traps






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






9. Soft coal - with the highest energy content






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






11. Marine shale - limestone - or oil shale






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






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






14. 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.






15. 125000 Btu per gallon






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






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






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

19. For heating - cooking - and making plastics






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






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






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






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






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






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






26. Intermediate between hard coal and peat






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






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






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






30. Salt or cemented sandstone






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






32. Energy






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






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






35. Soot - sulfur oxides - nitrogen oxides - mercury






36. Peat - formed from plants.






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






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






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






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






41. Fuel for cars






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






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






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






45. Traps formed by folding or faulting of rock layers






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






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






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






49. Fuel for jets and tractors






50. 1 Btu = 2.931x10-4 kWh
