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. Volumetric energy density






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






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






4. Replenish themselves or are continuously present






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






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






7. Semi-permeable dams






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






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






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






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






12. Compacting biomass through high temperatures - VED goes up






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






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






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






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






17. Solid biomass to liquid biomass with chemicals and heat






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






19. Bacteria ferments biomass with sugars






20. Water conservation - jobs - energy -






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






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






23. Burning to get heat and electricity






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






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






26. 3 factors that affect volatility






27. Hard coal - highest rank - 96% carbon






28. Solar cells to convert solar energy directly to electricity






29. 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






30. Crops and crop residue






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






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






33. Soft coal - reduced water (3%)






34. Burning biomass






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






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






37. 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






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






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






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






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






42. Pockets of hot water/steam underground






43. Solar energy heats water which turns a turbine






44. Burning rubbish/garbage






45. Burning wood






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






47. Difference between high and low tide






48. Hydrogen sulfide pollution - sources are often national treasures






49. Volcanoes - hot springs - geysers






50. Off shore wind is the most efficient
