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. Near the poles - tight openings - high tidal range






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






3. Burning to get heat and electricity






4. Water conservation - jobs - energy -






5. 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






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






7. Hydrogen sulfide pollution - sources are often national treasures






8. Bacteria ferments biomass with sugars






9. Solid biomass to liquid biomass with chemicals and heat






10. Difference between high and low tide






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






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






13. Hard coal - highest rank - 96% carbon






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






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






16. 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






17. Soft coal - reduced water (3%)






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






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






20. Volumetric energy density






21. Solar cells to convert solar energy directly to electricity






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






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






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






25. Compacting biomass through high temperatures - VED goes up






26. Volcanoes - hot springs - geysers






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






28. Off shore wind is the most efficient






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






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






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






32. Burning biomass






33. Solar energy heats water which turns a turbine






34. Semi-permeable dams






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






36. 3 factors that affect volatility






37. Crops and crop residue






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






39. Accumulation of organic material by living things






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






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






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






43. Burning wood






44. Replenish themselves or are continuously present






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






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






47. Pockets of hot water/steam underground






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






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






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