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






2. Burning rubbish/garbage






3. Burning wood






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






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






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






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






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






9. Burning biomass






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






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






12. Soft coal - reduced water (3%)






13. Off shore wind is the most efficient






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






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






16. Compacting biomass through high temperatures - VED goes up






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






18. Solar cells to convert solar energy directly to electricity






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






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






21. 3 factors that affect volatility






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






23. Solar energy heats water which turns a turbine






24. Solid biomass to liquid biomass with chemicals and heat






25. Volumetric energy density






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






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






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






29. 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






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






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






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






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






34. Burning to get heat and electricity






35. 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






36. Accumulation of organic material by living things






37. Difference between high and low tide






38. Hydrogen sulfide pollution - sources are often national treasures






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






40. Replenish themselves or are continuously present






41. Semi-permeable dams






42. Volcanoes - hot springs - geysers






43. Bacteria ferments biomass with sugars






44. Crops and crop residue






45. Hard coal - highest rank - 96% carbon






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






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






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






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






50. Pockets of hot water/steam underground
