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 flows to the surface from an underground reservoir when a well is dug.






2. 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.






3. Heat - pressure - dearth of oxygen






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






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






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






7. Hard coal - with the second highest energy content






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






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






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






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






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






13. For lubricating motors






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






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






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






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






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






19. A mixture of of hydrocarbons and organic compounds






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






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






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






23. Oil with little or no sulfur






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






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






26. Soft coal - with the highest energy content






27. For heating - cooking - and making plastics






28. 1 Btu = 2.931x10-4 kWh






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






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






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






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






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






34. Traps formed by folding or faulting of rock layers






35. Fuel for jets and tractors






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

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






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






39. Peat - formed from plants.






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






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






42. Soot - sulfur oxides - nitrogen oxides - mercury






43. 125000 Btu per gallon






44. Fuel for trucks






45. 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.






46. 1 Therm = 100000 Btu






47. Structural traps and stratigraphic traps






48. Salt or cemented sandstone






49. Intermediate between hard coal and peat






50. Fuel for cars
