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. Peat - formed from plants.






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






3. Heat - pressure - dearth of oxygen






4. Refined natural gas that contains pure methane.






5. 125000 Btu per gallon






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






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






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






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






10. Traps formed by folding or faulting of rock layers






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






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






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






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






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






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






17. Soot - sulfur oxides - nitrogen oxides - mercury






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






19. 22% of energy consumed in the U.S. comes from the burning of natural gas.






20. Salt or cemented sandstone






21. Fuel for jets and tractors






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






23. For lubricating motors






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






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






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






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






28. Marine shale - limestone - or oil shale






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






30. A mixture of of hydrocarbons and organic compounds






31. 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.






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






33. 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.






34. Hard coal - with the second highest energy content






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






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






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






38. For heating - cooking - and making plastics






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






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






41. Soft coal - with the highest energy content






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






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






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






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






46. Structural traps and stratigraphic traps






47. Energy






48. 1 Therm = 100000 Btu






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






50. Fuel for trucks
