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. Slow decay of radioactive particles in rocks gives off heat






3. Pockets of hot water/steam underground






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






5. Solar cells to convert solar energy directly to electricity






6. 3 factors that affect volatility






7. Replenish themselves or are continuously present






8. Difference between high and low tide






9. Soft coal - reduced water (3%)






10. Burning to get heat and electricity






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






12. Crops and crop residue






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






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






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






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






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






18. Hydrogen sulfide pollution - sources are often national treasures






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






20. Solar energy heats water which turns a turbine






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






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






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






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






25. Semi-permeable dams






26. Burning wood






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






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






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






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






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






32. Burning biomass






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






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






35. Bacteria ferments biomass with sugars






36. Hard coal - highest rank - 96% carbon






37. Solid biomass to liquid biomass with chemicals and heat






38. Burning rubbish/garbage






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






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






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






42. Off shore wind is the most efficient






43. 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






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






45. Volumetric energy density






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






47. Water conservation - jobs - energy -






48. Accumulation of organic material by living things






49. Volcanoes - hot springs - geysers






50. 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
