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 rubbish/garbage






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






3. Pockets of hot water/steam underground






4. Compacting biomass through high temperatures - VED goes up






5. Burning biomass






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






7. Solar cells to convert solar energy directly to electricity






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






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






10. Volumetric energy density






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






12. Hard coal - highest rank - 96% carbon






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






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






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






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






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






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






19. Crops and crop residue






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






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






22. 3 factors that affect volatility






23. Off shore wind is the most efficient






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






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






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






27. 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






28. Burning wood






29. Water conservation - jobs - energy -






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






31. Burning to get heat and electricity






32. Soft coal - reduced water (3%)






33. Semi-permeable dams






34. Solar energy heats water which turns a turbine






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






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






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






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






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






40. Volcanoes - hot springs - geysers






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






42. Hydrogen sulfide pollution - sources are often national treasures






43. Difference between high and low tide






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






45. Bacteria ferments biomass with sugars






46. Replenish themselves or are continuously present






47. Accumulation of organic material by living things






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






49. 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






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