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. Refined natural gas that contains pure methane.






2. Hard coal - with the second highest energy content






3. Peat - formed from plants.






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






5. For heating - cooking - and making plastics






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






7. Fuel for cars






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






9. 1 Btu = 1055 J






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






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






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

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






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






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






16. 125000 Btu per gallon






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






18. Fuel for trucks






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






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






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






22. For lubricating motors






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






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






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






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






27. Fuel for jets and tractors






28. Salt or cemented sandstone






29. Soft coal - with the highest energy content






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






31. Heat - pressure - dearth of oxygen






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






33. Marine shale - limestone - or oil shale






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






35. 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.






36. Traps formed by folding or faulting of rock layers






37. Intermediate between hard coal and peat






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






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






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






41. Oil with little or no sulfur






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






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






44. Soot - sulfur oxides - nitrogen oxides - mercury






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






46. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






47. Energy






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






49. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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