Renewable And Nonrenewable Energy

Subject : 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. Hard to transport - natural gas needs to be changed into a liquid to be efficiently transported - drill sites could be terrorist targets - disorients whales - harms the environment - hard to find/pump - dangerous - oil air pollution






2. Hard coal - highest rank - 96% carbon






3. Hydrogen sulfide pollution - sources are often national treasures






4. 3 factors that affect volatility






5. Semi-permeable dams






6. Volumetric energy density






7. Solar cells to convert solar energy directly to electricity






8. Solid biomass to liquid biomass with chemicals and heat






9. Energy that can be obtained from movement of water due to the gravitational pull of the sun - moon - and earth's rotation






10. Easy to store - 90% of world's commercially traded energy is oil/natural gas - secondary recovery - cracking - profitable - jobs - natural gas = no air pollution






11. Remains of once living organisms preserved and altered by geological forces






12. Pockets of hot water/steam underground






13. Resevoir - dam - penstock - turbine - generator - outflow - inflow






14. Microscopic dying organisms sink to the bottom of the ocean secreting drops of oil - shale is formed from mud and sediment with oil droplets - over time the droplets rise into a pocket in the ground






15. Compacting biomass through high temperatures - VED goes up






16. Same as pyrolysis process but with more heat and less gas - goes all the way to gas






17. Unreliable - energy companies only see it as supplemental power - strong winds are usually not near people or grids






18. Volcanoes - hot springs - geysers






19. Slow decay of radioactive particles in rocks gives off heat






20. Wood - crops grown for energy - crop residues - animal waste - algae - some garbage






21. Finite supply being used faster than they can be replenished






22. Radiant energy form the sun heats earth and atmosphere - causes warming of the air and wind cycle






23. Near the poles - tight openings - high tidal range






24. Secondary pollution (toxic materials and alcohols - blocking the sun for some animals) - bird death ray - startup cost






25. Water conservation - jobs - energy -






26. Burning rubbish/garbage






27. Burning to get heat and electricity






28. Replenish themselves or are continuously present






29. Air heated more from ground near equator - creates global jet streams






30. Air cools more quickly over land than water - wind cycle goes the opposite way as day winds






31. Naturally occurring substance that can potentially be extracted using modern technology






32. Solar radiation from the sun is converted to heat or electricity






33. Burning wood






34. Lowest rank coal - less water and higher proportion of burnable materials than peat (40% water)






35. Effecting the tide - high startup cost - low efficiency in some cases






36. Bacteria break down with without oxygen - product is LFGs






37. Accumulation of organic material by living things






38. Adding hydrocarbons by breaking down non-useful parts of oil






39. Air is heated from ground - warm air flows upward - cold air replaces it






40. Burning biomass






41. Solar energy heats water which turns a turbine






42. Crops and crop residue






43. Difference between high and low tide






44. Heat is recovered as steam or hot water to create electricity or heat buildings






45. Bacteria ferments biomass with sugars






46. Changes landscape - land reclamation - acid min drainage - black lung - foundation damage (subsidence) - mountain top removal - insurance - most danger






47. Water floods - peat and sediment is pushed down - peat is pressed down for millions of years - coal is formed






48. Known deposits which can be extracted from profitably using modern technology under certain economic conditions






49. Secondary Pollution -Toxic materials and alcohols -Blocking the sun for some animals -No direct pollution though! Bird death ray - Startup cost






50. Organic materials are changed to lighter - more volatile hydrocarbons
