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. Replenish themselves or are continuously present






2. Burning to get heat and electricity






3. Burning rubbish/garbage






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






5. Volumetric energy density






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






7. Volcanoes - hot springs - geysers






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






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






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






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






12. 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






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






14. 3 factors that affect volatility






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






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






17. Compacting biomass through high temperatures - VED goes up






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






19. Solar energy heats water which turns a turbine






20. Solar cells to convert solar energy directly to electricity






21. Difference between high and low tide






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






23. Burning biomass






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






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






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






27. Off shore wind is the most efficient






28. Bacteria ferments biomass with sugars






29. Accumulation of organic material by living things






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






31. Soft coal - reduced water (3%)






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






33. Crops and crop residue






34. High tidal range - mouths of bays and estuaries - ideally near poles






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






36. Solid biomass to liquid biomass with chemicals and heat






37. Burning wood






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






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






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






41. 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






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






43. Semi-permeable dams






44. Hard coal - highest rank - 96% carbon






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






46. Water conservation - jobs - energy -






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






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






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






50. Pockets of hot water/steam underground
