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






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






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






4. Volumetric energy density






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






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






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






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






9. Crops and crop residue






10. Semi-permeable dams






11. Burning biomass






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






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






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






16. Pockets of hot water/steam underground






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






18. Water conservation - jobs - energy -






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






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






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






22. Replenish themselves or are continuously present






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






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






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






26. Accumulation of organic material by living things






27. Soft coal - reduced water (3%)






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






29. Burning to get heat and electricity






30. 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






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






32. 3 factors that affect volatility






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






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






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






36. Burning wood






37. Burning rubbish/garbage






38. Difference between high and low tide






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






40. 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






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






42. Hard coal - highest rank - 96% carbon






43. Hydrogen sulfide pollution - sources are often national treasures






44. Compacting biomass through high temperatures - VED goes up






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






46. Bacteria ferments biomass with sugars






47. Solar energy heats water which turns a turbine






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






49. Volcanoes - hot springs - geysers






50. Solid biomass to liquid biomass with chemicals and heat
