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






2. Peat - formed from plants.






3. Energy






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






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






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






7. Traps formed by folding or faulting of rock layers






8. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






9. Heat - pressure - dearth of oxygen






10. For heating - cooking - and making plastics






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






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






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






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






15. Salt or cemented sandstone






16. Oil with little or no sulfur






17. Fuel for jets and tractors






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






19. 1 Therm = 100000 Btu






20. Refined natural gas that contains pure methane.






21. 1 Btu = 2.931x10-4 kWh






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






23. 125000 Btu per gallon






24. 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.






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






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






27. Fuel for trucks






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






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






30. 1 Btu = 1055 J






31. Fuel for cars






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






33. Intermediate between hard coal and peat






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






35. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






38. Structural traps and stratigraphic traps






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






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






41. 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.






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






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






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






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






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






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






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






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






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