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. Off shore wind is the most efficient






2. Semi-permeable dams






3. Solar cells to convert solar energy directly to electricity






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






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






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






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






8. Solar energy heats water which turns a turbine






9. Volcanoes - hot springs - geysers






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






11. Difference between high and low tide






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






13. Water conservation - jobs - energy -






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






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






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






17. Hard coal - highest rank - 96% carbon






18. Soft coal - reduced water (3%)






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






20. 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






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






22. Hydrogen sulfide pollution - sources are often national treasures






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. Near the poles - tight openings - high tidal range






25. Pockets of hot water/steam underground






26. Burning wood






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






28. Burning rubbish/garbage






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






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






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






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






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






34. Replenish themselves or are continuously present






35. Compacting biomass through high temperatures - VED goes up






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






37. Burning biomass






38. Bacteria ferments biomass with sugars






39. Solid biomass to liquid biomass with chemicals and heat






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






41. 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






42. Burning to get heat and electricity






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






44. Accumulation of organic material by living things






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






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






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






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






49. Crops and crop residue






50. 3 factors that affect volatility
