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. Semi-permeable dams






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






3. Pockets of hot water/steam underground






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






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






6. Hard coal - highest rank - 96% carbon






7. Replenish themselves or are continuously present






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






9. Solar cells to convert solar energy directly to electricity






10. Solid biomass to liquid biomass with chemicals and heat






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






12. Solar energy heats water which turns a turbine






13. Burning biomass






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






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






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






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






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






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






20. Accumulation of organic material by living things






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






22. Burning wood






23. Burning rubbish/garbage






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






25. Off shore wind is the most efficient






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






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. Soft coal - reduced water (3%)






29. Volcanoes - hot springs - geysers






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






31. Burning to get heat and electricity






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






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






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






35. Crops and crop residue






36. 3 factors that affect volatility






37. Hydrogen sulfide pollution - sources are often national treasures






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






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






40. Difference between high and low tide






41. Compacting biomass through high temperatures - VED goes up






42. 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






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






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






45. Bacteria ferments biomass with sugars






46. Water conservation - jobs - energy -






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






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






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






50. Volumetric energy density
