Renewable And Nonrenewable Energy

Subject : science
Instructions:
  • Answer 50 questions in 30 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. Finite supply being used faster than they can be replenished






2. Off shore wind is the most efficient






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






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






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






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






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






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






9. Volumetric energy density






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






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. 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






13. 3 factors that affect volatility






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






15. Burning wood






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






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






18. Solar cells to convert solar energy directly to electricity






19. Soft coal - reduced water (3%)






20. Compacting biomass through high temperatures - VED goes up






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






22. Volcanoes - hot springs - geysers






23. Crops and crop residue






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






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






26. Hydrogen sulfide pollution - sources are often national treasures






27. Accumulation of organic material by living things






28. Pockets of hot water/steam underground






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






30. Bacteria ferments biomass with sugars






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






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






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






34. Solar energy heats water which turns a turbine






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






36. Hard coal - highest rank - 96% carbon






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






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






39. Burning biomass






40. Burning rubbish/garbage






41. Water conservation - jobs - energy -






42. Replenish themselves or are continuously present






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






44. Semi-permeable dams






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






46. Difference between high and low tide






47. Solid biomass to liquid biomass with chemicals and heat






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






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






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