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






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






3. Replenish themselves or are continuously present






4. Accumulation of organic material by living things






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






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






7. Hard coal - highest rank - 96% carbon






8. Semi-permeable dams






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






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






11. Off shore wind is the most efficient






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






13. 3 factors that affect volatility






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






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






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






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






18. Compacting biomass through high temperatures - VED goes up






19. Difference between high and low tide






20. Solar cells to convert solar energy directly to electricity






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






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






23. Burning biomass






24. Solid biomass to liquid biomass with chemicals and heat






25. Volcanoes - hot springs - geysers






26. Burning wood






27. Burning to get heat and electricity






28. Bacteria ferments biomass with sugars






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






30. Soft coal - reduced water (3%)






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






32. 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






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






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






35. Solar energy heats water which turns a turbine






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






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






38. 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






39. Hydrogen sulfide pollution - sources are often national treasures






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






41. Crops and crop residue






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






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






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






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






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






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






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






49. Volumetric energy density






50. Burning rubbish/garbage
