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






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






3. 1 Therm = 100000 Btu






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






5. Hard coal - with the second highest energy content






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






7. 125000 Btu per gallon






8. Intermediate between hard coal and peat






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






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






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






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






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


14. A mixture of of hydrocarbons and organic compounds






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






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






17. 1 Btu = 1055 J






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






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






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






21. Peat - formed from plants.






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






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






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






25. Traps formed by folding or faulting of rock layers






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






27. For lubricating motors






28. Soft coal - with the highest energy content






29. Fuel for trucks






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






31. For heating - cooking - and making plastics






32. 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.






33. Marine shale - limestone - or oil shale






34. Soot - sulfur oxides - nitrogen oxides - mercury






35. Fuel for jets and tractors






36. 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.






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






38. Fuel for cars






39. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






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






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






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






45. 1 Btu = 2.931x10-4 kWh






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






47. Refined natural gas that contains pure methane.






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






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






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