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






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






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






4. Energy






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






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






7. For heating - cooking - and making plastics






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






9. For lubricating motors






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






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






12. Marine shale - limestone - or oil shale






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






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






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






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






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






18. Structural traps and stratigraphic traps






19. Refined natural gas that contains pure methane.






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






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






22. 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.






23. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






26. Heat - pressure - dearth of oxygen






27. Fuel for jets and tractors






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






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






30. Soft coal - with the highest energy content






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






32. Traps formed by folding or faulting of rock layers






33. 1 Btu = 2.931x10-4 kWh






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

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






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






37. 1 Btu = 1055 J






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






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






40. Peat - formed from plants.






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






42. Oil with little or no sulfur






43. 125000 Btu per gallon






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






45. Hard coal - with the second highest energy content






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






47. Fuel for cars






48. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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