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






3. Hard coal - with the second highest energy content






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






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






6. Oil with little or no sulfur






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






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






9. Intermediate between hard coal and peat






10. Peat - formed from plants.






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






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






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






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






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






16. 125000 Btu per gallon






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






18. A mixture of of hydrocarbons and organic compounds






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






20. 1 Btu = 2.931x10-4 kWh






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






22. Fuel for cars






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






24. Salt or cemented sandstone






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






26. Energy






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






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






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






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






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






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






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






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






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






36. Soot - sulfur oxides - nitrogen oxides - mercury






37. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






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






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






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






43. 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.






44. For lubricating motors






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






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






47. Soft coal - with the highest energy content






48. Traps formed by folding or faulting of rock layers






49. Fuel for jets and tractors






50. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.
