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






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






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






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






5. Structural traps and stratigraphic traps






6. 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.






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






8. Oil with little or no sulfur






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






10. For lubricating motors






11. Peat - formed from plants.






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






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






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






15. For heating - cooking - and making plastics






16. Marine shale - limestone - or oil shale






17. Soft coal - with the highest energy content






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






19. Salt or cemented sandstone






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






21. Traps formed by folding or faulting of rock layers






22. Fuel for trucks






23. Fuel for jets and tractors






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






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






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






27. Soot - sulfur oxides - nitrogen oxides - mercury






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






29. Fuel for cars






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






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

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






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






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






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






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






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






38. Intermediate between hard coal and peat






39. Heat - pressure - dearth of oxygen






40. Refined natural gas that contains pure methane.






41. 1 Btu = 2.931x10-4 kWh






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






43. Hard coal - with the second highest energy content






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






45. Energy






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






47. 22% of energy consumed in the U.S. comes from the burning of natural gas.






48. 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.






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






50. 1 Btu = 1055 J
