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






2. Accumulation of organic material by living things






3. 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






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






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






6. Burning rubbish/garbage






7. Soft coal - reduced water (3%)






8. Solar energy heats water which turns a turbine






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






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






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






12. Crops and crop residue






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






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






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






16. Volumetric energy density






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






18. Burning biomass






19. Solar cells to convert solar energy directly to electricity






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






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






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






23. Compacting biomass through high temperatures - VED goes up






24. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






28. Difference between high and low tide






29. Burning wood






30. Bacteria ferments biomass with sugars






31. Hard coal - highest rank - 96% carbon






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






33. Replenish themselves or are continuously present






34. Solid biomass to liquid biomass with chemicals and heat






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






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






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






38. Pockets of hot water/steam underground






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






40. 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






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






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






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






44. Semi-permeable dams






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






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






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






48. 3 factors that affect volatility






49. Volcanoes - hot springs - geysers






50. Water conservation - jobs - energy -
