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






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






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






4. Marine shale - limestone - or oil shale






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






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






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






8. 1 Btu = 1055 J






9. Fuel for cars






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






11. Energy






12. Hard coal - with the second highest energy content






13. 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.






14. Soot - sulfur oxides - nitrogen oxides - mercury






15. For lubricating motors






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






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






18. Soft coal - with the highest energy content






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






20. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






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






23. 1 Therm = 100000 Btu






24. Peat - formed from plants.






25. Heat - pressure - dearth of oxygen






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






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






28. 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.






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






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






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






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






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






34. Refined natural gas that contains pure methane.






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






36. Fuel for jets and tractors






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






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






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






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






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






42. Salt or cemented sandstone






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






44. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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






47. A mixture of of hydrocarbons and organic compounds






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






49. Fuel for trucks






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