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. Burning to get heat and electricity






2. Volcanoes - hot springs - geysers






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






4. Water conservation - jobs - energy -






5. 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






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






7. Difference between high and low tide






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






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






10. Accumulation of organic material by living things






11. Soft coal - reduced water (3%)






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






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






14. 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






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






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






17. Crops and crop residue






18. Hard coal - highest rank - 96% carbon






19. 3 factors that affect volatility






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






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






22. Solid biomass to liquid biomass with chemicals and heat






23. Off shore wind is the most efficient






24. Replenish themselves or are continuously present






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






26. Bacteria ferments biomass with sugars






27. Solar energy heats water which turns a turbine






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






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






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






31. Pockets of hot water/steam underground






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






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






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






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






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






37. Burning rubbish/garbage






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






39. Burning biomass






40. Burning wood






41. Volumetric energy density






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






43. Semi-permeable dams






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






45. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






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






50. Compacting biomass through high temperatures - VED goes up
