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. Replenish themselves or are continuously present






2. 3 factors that affect volatility






3. Pockets of hot water/steam underground






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






5. Solar energy heats water which turns a turbine






6. Crops and crop residue






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






8. Accumulation of organic material by living things






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






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






11. Solid biomass to liquid biomass with chemicals and heat






12. Hydrogen sulfide pollution - sources are often national treasures






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






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






15. Difference between high and low tide






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






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






18. Burning to get heat and electricity






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






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






21. Bacteria ferments biomass with sugars






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






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






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






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






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






27. Burning biomass






28. Off shore wind is the most efficient






29. Compacting biomass through high temperatures - VED goes up






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






31. Hard coal - highest rank - 96% carbon






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






33. 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






34. Solar cells to convert solar energy directly to electricity






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






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






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






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






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






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






41. Burning wood






42. Volcanoes - hot springs - geysers






43. Water conservation - jobs - energy -






44. Burning rubbish/garbage






45. 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






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






47. Soft coal - reduced water (3%)






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






49. Volumetric energy density






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