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






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






3. Soft coal - with the highest energy content






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






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






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






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






8. Traps formed by folding or faulting of rock layers






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






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






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






12. 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.






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






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






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

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






17. 125000 Btu per gallon






18. Peat - formed from plants.






19. Fuel for trucks






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






21. 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.






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






23. Oil with little or no sulfur






24. 1 Therm = 100000 Btu






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






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






27. Soot - sulfur oxides - nitrogen oxides - mercury






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






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






30. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






32. 1 Btu = 2.931x10-4 kWh






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






34. Marine shale - limestone - or oil shale






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






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






37. Fuel for cars






38. Intermediate between hard coal and peat






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






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






41. Structural traps and stratigraphic traps






42. Hard coal - with the second highest energy content






43. 1 Btu = 1055 J






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






45. For heating - cooking - and making plastics






46. Heat - pressure - dearth of oxygen






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






48. Fuel for jets and tractors






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






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