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






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






3. Burning to get heat and electricity






4. Volumetric energy density






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






6. Difference between high and low tide






7. 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






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






9. Compacting biomass through high temperatures - VED goes up






10. Hydrogen sulfide pollution - sources are often national treasures






11. Burning wood






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






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






14. Burning rubbish/garbage






15. Off shore wind is the most efficient






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






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






18. Solar cells to convert solar energy directly to electricity






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






20. Crops and crop residue






21. Soft coal - reduced water (3%)






22. 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






23. Solar energy heats water which turns a turbine






24. Semi-permeable dams






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






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






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






28. Water conservation - jobs - energy -






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






30. Replenish themselves or are continuously present






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






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






33. Hard coal - highest rank - 96% carbon






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






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






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






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






38. Solid biomass to liquid biomass with chemicals and heat






39. Volcanoes - hot springs - geysers






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






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






42. Pockets of hot water/steam underground






43. Accumulation of organic material by living things






44. Burning biomass






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






46. Bacteria ferments biomass with sugars






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






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






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






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