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






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






3. Compacting biomass through high temperatures - VED goes up






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






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






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






7. Solar cells to convert solar energy directly to electricity






8. Replenish themselves or are continuously present






9. 3 factors that affect volatility






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






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






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






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






14. Burning to get heat and electricity






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






16. Water conservation - jobs - energy -






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






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






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






20. Difference between high and low tide






21. Volcanoes - hot springs - geysers






22. Burning biomass






23. Off shore wind is the most efficient






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






25. Bacteria ferments biomass with sugars






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






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






28. Burning rubbish/garbage






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






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






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






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






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






34. Hydrogen sulfide pollution - sources are often national treasures






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






36. Solid biomass to liquid biomass with chemicals and heat






37. Volumetric energy density






38. Hard coal - highest rank - 96% carbon






39. 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






40. Crops and crop residue






41. Semi-permeable dams






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






43. Solar energy heats water which turns a turbine






44. Burning wood






45. Accumulation of organic material by living things






46. Pockets of hot water/steam underground






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






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






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






50. Soft coal - reduced water (3%)
