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






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






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






4. Soot - sulfur oxides - nitrogen oxides - mercury






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






6. Fuel for jets and tractors






7. Soft coal - with the highest energy content






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






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


10. Fuel for trucks






11. For heating - cooking - and making plastics






12. 1 Btu = 1055 J






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






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






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






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






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






18. Heat - pressure - dearth of oxygen






19. 1 Btu = 2.931x10-4 kWh






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






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






22. Structural traps and stratigraphic traps






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






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






25. Hard coal - with the second highest energy content






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






27. Intermediate between hard coal and peat






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






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






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






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






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






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






34. Oil with little or no sulfur






35. For lubricating motors






36. 125000 Btu per gallon






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






38. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






39. Fuel for cars






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






41. Marine shale - limestone - or oil shale






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






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






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






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






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






47. Salt or cemented sandstone






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






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






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