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






2. Peat - formed from plants.






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






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


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






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






7. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






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






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






12. Marine shale - limestone - or oil shale






13. 125000 Btu per gallon






14. Energy






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






16. 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.






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






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






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






20. Soft coal - with the highest energy content






21. Structural traps and stratigraphic traps






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






23. 1 Btu = 2.931x10-4 kWh






24. For lubricating motors






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






26. A mixture of of hydrocarbons and organic compounds






27. Salt or cemented sandstone






28. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






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






32. 1 Btu = 1055 J






33. 1 Therm = 100000 Btu






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






35. Fuel for trucks






36. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






37. Fuel for jets and tractors






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






39. Hard coal - with the second highest energy content






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






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






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






43. For heating - cooking - and making plastics






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






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






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






47. Intermediate between hard coal and peat






48. Heat - pressure - dearth of oxygen






49. Refined natural gas that contains pure methane.






50. Traps formed by folding or faulting of rock layers
