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






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






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






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






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






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






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






8. Peat - formed from plants.






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






10. Structural traps and stratigraphic traps






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






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






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






14. Soot - sulfur oxides - nitrogen oxides - mercury






15. Hard coal - with the second highest energy content






16. Fuel for jets and tractors






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






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






19. 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.






20. 125000 Btu per gallon






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






22. 1 Therm = 100000 Btu






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






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






25. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






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


29. 1 Btu = 1055 J






30. Traps formed by folding or faulting of rock layers






31. Heat - pressure - dearth of oxygen






32. 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.






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






34. 1 Btu = 2.931x10-4 kWh






35. Soft coal - with the highest energy content






36. Energy






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






38. Refined natural gas that contains pure methane.






39. Marine shale - limestone - or oil shale






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






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






42. Oil with little or no sulfur






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






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






45. Fuel for trucks






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






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






48. Intermediate between hard coal and peat






49. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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