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. Volcanoes - hot springs - geysers






2. Soft coal - reduced water (3%)






3. Accumulation of organic material by living things






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






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






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






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






8. Burning rubbish/garbage






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






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






11. 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






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






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






14. Crops and crop residue






15. Difference between high and low tide






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






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






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






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






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






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






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






23. Hydrogen sulfide pollution - sources are often national treasures






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






25. Hard coal - highest rank - 96% carbon






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






27. Compacting biomass through high temperatures - VED goes up






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






29. Pockets of hot water/steam underground






30. Burning wood






31. Bacteria ferments biomass with sugars






32. 3 factors that affect volatility






33. Solar energy heats water which turns a turbine






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






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






36. 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






37. Burning biomass






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






39. Solid biomass to liquid biomass with chemicals and heat






40. Water conservation - jobs - energy -






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






42. Off shore wind is the most efficient






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






44. Volumetric energy density






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






46. Replenish themselves or are continuously present






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






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






49. Burning to get heat and electricity






50. Semi-permeable dams
