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

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






3. 1 Btu = 2.931x10-4 kWh






4. Hard coal - with the second highest energy content






5. Oil with little or no sulfur






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






7. For heating - cooking - and making plastics






8. Fuel for cars






9. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






11. Structural traps and stratigraphic traps






12. Soft coal - with the highest energy content






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






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






15. Refined natural gas that contains pure methane.






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






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






18. 1 Btu = 1055 J






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






20. Peat - formed from plants.






21. Heat - pressure - dearth of oxygen






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






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






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






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






26. 125000 Btu per gallon






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






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






29. Energy






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






31. 1 Therm = 100000 Btu






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






33. For lubricating motors






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






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






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






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






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






39. Traps formed by folding or faulting of rock layers






40. Marine shale - limestone - or oil shale






41. Fuel for jets and tractors






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






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






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






45. 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.






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






47. Intermediate between hard coal and peat






48. Soot - sulfur oxides - nitrogen oxides - mercury






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






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