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






2. Solar energy heats water which turns a turbine






3. Volumetric energy density






4. Replenish themselves or are continuously present






5. Crops and crop residue






6. Bacteria ferments biomass with sugars






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






8. Solar cells to convert solar energy directly to electricity






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






10. Volcanoes - hot springs - geysers






11. Compacting biomass through high temperatures - VED goes up






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






13. Semi-permeable dams






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






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






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






17. Hydrogen sulfide pollution - sources are often national treasures






18. 3 factors that affect volatility






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






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






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






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






23. Hard coal - highest rank - 96% carbon






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






25. Off shore wind is the most efficient






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






27. 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






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






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. Difference between high and low tide






31. Burning to get heat and electricity






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






33. Water conservation - jobs - energy -






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






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






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






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






38. Burning biomass






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






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






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






42. Accumulation of organic material by living things






43. Pockets of hot water/steam underground






44. Burning wood






45. Burning rubbish/garbage






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






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






48. Soft coal - reduced water (3%)






49. Solid biomass to liquid biomass with chemicals and heat






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