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






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






3. 1 Therm = 100000 Btu






4. Fuel for cars






5. Energy






6. Soft coal - with the highest energy content






7. Traps formed by folding or faulting of rock layers






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






9. A mixture of of hydrocarbons and organic compounds






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






11. Peat - formed from plants.






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






13. Salt or cemented sandstone






14. 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.






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






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






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






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






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






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






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






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






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






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






25. Fuel for jets and tractors






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






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






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






29. Fuel for trucks






30. Heat - pressure - dearth of oxygen






31. 70%-90% methane - and small proportions of ethane - propane - and butane. Some carbon dioxide. Trace amounts of other gases.






32. Refined natural gas that contains pure methane.






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






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






35. For lubricating motors






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

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






38. Intermediate between hard coal and peat






39. Marine shale - limestone - or oil shale






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






41. Structural traps and stratigraphic traps






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






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






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






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






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






47. 125000 Btu per gallon






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






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






50. Hard coal - with the second highest energy content
