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






2. Heat - pressure - dearth of oxygen






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






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






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






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






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






8. 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.






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






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






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






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






13. Fuel for cars






14. Fuel for trucks






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






16. Refined natural gas that contains pure methane.






17. Salt or cemented sandstone






18. A mixture of of hydrocarbons and organic compounds






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






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






21. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






23. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






26. For heating - cooking - and making plastics






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






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






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






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






31. 125000 Btu per gallon






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






33. Traps formed by folding or faulting of rock layers






34. Energy






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






36. Structural traps and stratigraphic traps






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






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






39. Oil with little or no sulfur






40. Fuel for jets and tractors






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






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






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

44. Marine shale - limestone - or oil shale






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






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






47. 1 Btu = 1055 J






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






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






50. Peat - formed from plants.
