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. Heat - pressure - dearth of oxygen






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






3. Energy






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






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






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






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






8. Fuel for jets and tractors






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






10. 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.






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






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






13. 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.






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






15. Salt or cemented sandstone






16. 1 Btu = 2.931x10-4 kWh






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






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






19. Fuel for trucks






20. 1 Btu = 1055 J






21. 1 Therm = 100000 Btu






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






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






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






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






26. Hard coal - with the second highest energy content






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






28. Soft coal - with the highest energy content






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






30. Refined natural gas that contains pure methane.






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






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






33. Marine shale - limestone - or oil shale






34. Intermediate between hard coal and peat






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






36. Oil with little or no sulfur






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

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






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






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






41. Traps formed by folding or faulting of rock layers






42. Soot - sulfur oxides - nitrogen oxides - mercury






43. For lubricating motors






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






45. A mixture of of hydrocarbons and organic compounds






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






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






48. 125000 Btu per gallon






49. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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