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. Accumulation of organic material by living things






2. 3 factors that affect volatility






3. Crops and crop residue






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






5. Pockets of hot water/steam underground






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






7. Solar cells to convert solar energy directly to electricity






8. Burning to get heat and electricity






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






10. Burning rubbish/garbage






11. 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






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






13. Difference between high and low tide






14. Bacteria ferments biomass with sugars






15. Burning biomass






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






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






18. Water conservation - jobs - energy -






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






20. Volcanoes - hot springs - geysers






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






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






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






24. Solar energy heats water which turns a turbine






25. Replenish themselves or are continuously present






26. Soft coal - reduced water (3%)






27. Compacting biomass through high temperatures - VED goes up






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






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






30. 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






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






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






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






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






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






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






37. Hydrogen sulfide pollution - sources are often national treasures






38. Hard coal - highest rank - 96% carbon






39. Volumetric energy density






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






41. Solid biomass to liquid biomass with chemicals and heat






42. Burning wood






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






44. Semi-permeable dams






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






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






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






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






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






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