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. Heat - pressure - dearth of oxygen






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






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






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






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






6. Energy






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






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






9. Hard coal - with the second highest energy content






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






11. Traps formed by folding or faulting of rock layers






12. Salt or cemented sandstone






13. Peat - formed from plants.






14. 1 Btu = 2.931x10-4 kWh






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






16. 1 Btu = 1055 J






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






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






19. For lubricating motors






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






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






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






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






24. Soft coal - with the highest energy content






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






26. 125000 Btu per gallon






27. A mixture of of hydrocarbons and organic compounds






28. Fuel for trucks






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






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






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






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






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






34. For heating - cooking - and making plastics






35. Marine shale - limestone - or oil shale






36. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






37. 1 Therm = 100000 Btu






38. Fuel for cars






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






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






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






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






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






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






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

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






47. Soot - sulfur oxides - nitrogen oxides - mercury






48. Oil with little or no sulfur






49. 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.






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