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






2. Soot - sulfur oxides - nitrogen oxides - mercury






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

4. Fuel for jets and tractors






5. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






6. Soft coal - with the highest energy content






7. 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.






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






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






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






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






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






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






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






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






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






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






18. Fuel for cars






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






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






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






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






23. A mixture of of hydrocarbons and organic compounds






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






25. For lubricating motors






26. 1 Btu = 1055 J






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






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






29. Heat - pressure - dearth of oxygen






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






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






32. Intermediate between hard coal and peat






33. Structural traps and stratigraphic traps






34. Fuel for trucks






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






36. Marine shale - limestone - or oil shale






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






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






39. Peat - formed from plants.






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






41. Traps formed by folding or faulting of rock layers






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






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






44. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






47. 125000 Btu per gallon






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






49. 1 Therm = 100000 Btu






50. Salt or cemented sandstone
