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. Volcanoes - hot springs - geysers






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






3. Soft coal - reduced water (3%)






4. Solar cells to convert solar energy directly to electricity






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






6. Semi-permeable dams






7. Volumetric energy density






8. Water conservation - jobs - energy -






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






10. Replenish themselves or are continuously present






11. Bacteria ferments biomass with sugars






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






13. Burning rubbish/garbage






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






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






16. Crops and crop residue






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






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






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






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






21. Burning wood






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






23. Accumulation of organic material by living things






24. Compacting biomass through high temperatures - VED goes up






25. Hydrogen sulfide pollution - sources are often national treasures






26. Solid biomass to liquid biomass with chemicals and heat






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






28. Solar energy heats water which turns a turbine






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






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






31. Hard coal - highest rank - 96% carbon






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






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






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






35. Off shore wind is the most efficient






36. Burning biomass






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






38. 3 factors that affect volatility






39. Burning to get heat and electricity






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






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






42. Difference between high and low tide






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






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






45. 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






46. Pockets of hot water/steam underground






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






48. 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






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






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