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






2. 1 Btu = 1055 J






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






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






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






6. Hard coal - with the second highest energy content






7. Energy






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


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






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






11. Fuel for trucks






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






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






14. 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.






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






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






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






18. Soft coal - with the highest energy content






19. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






20. A mixture of of hydrocarbons and organic compounds






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






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






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






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






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






26. Peat - formed from plants.






27. Heat - pressure - dearth of oxygen






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






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






30. For lubricating motors






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






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






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






34. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






36. Salt or cemented sandstone






37. Intermediate between hard coal and peat






38. Marine shale - limestone - or oil shale






39. For heating - cooking - and making plastics






40. Fuel for cars






41. Soot - sulfur oxides - nitrogen oxides - mercury






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






43. 125000 Btu per gallon






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






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






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






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






48. 1 Btu = 2.931x10-4 kWh






49. Refined natural gas that contains pure methane.






50. Fuel for jets and tractors
