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. Traps formed by folding or faulting of rock layers






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






3. Soft coal - with the highest energy content






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






5. 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.






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






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






8. Heat - pressure - dearth of oxygen






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






10. Peat - formed from plants.






11. Fuel for jets and tractors






12. For heating - cooking - and making plastics






13. Intermediate between hard coal and peat






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






15. Marine shale - limestone - or oil shale






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






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






18. 1 Btu = 1055 J






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

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






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






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






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






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






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






26. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






29. Salt or cemented sandstone






30. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






31. A mixture of of hydrocarbons and organic compounds






32. 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.






33. 1 Btu = 2.931x10-4 kWh






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






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






36. For lubricating motors






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






38. Refined natural gas that contains pure methane.






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






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






41. Fuel for cars






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






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






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






45. 1 Therm = 100000 Btu






46. Oil with little or no sulfur






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






48. Energy






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






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