CSET Earth Resources Fossil Fuels

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






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






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






4. Hard coal - with the second highest energy content






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






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






7. Soot - sulfur oxides - nitrogen oxides - mercury






8. 1 Btu = 2.931x10-4 kWh






9. For lubricating motors






10. Fuel for cars






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






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






13. Heat - pressure - dearth of oxygen






14. Fuel for trucks






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






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






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






18. 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.






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






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






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






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






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






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






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






26. Traps formed by folding or faulting of rock layers






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






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






29. Marine shale - limestone - or oil shale






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

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






32. 125000 Btu per gallon






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






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






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






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






37. 22% of energy consumed in the U.S. comes from the burning of natural gas.






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






39. Soft coal - with the highest energy content






40. Intermediate between hard coal and peat






41. Peat - formed from plants.






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






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






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






45. Refined natural gas that contains pure methane.






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






47. Fuel for jets and tractors






48. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






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






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