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. Pockets of hot water/steam underground






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






3. Volumetric energy density






4. Volcanoes - hot springs - geysers






5. Solar energy heats water which turns a turbine






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






7. Solar cells to convert solar energy directly to electricity






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






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






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






11. Hydrogen sulfide pollution - sources are often national treasures






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






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






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






15. Burning to get heat and electricity






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






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






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






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






20. Solid biomass to liquid biomass with chemicals and heat






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






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






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






24. Soft coal - reduced water (3%)






25. 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






26. Compacting biomass through high temperatures - VED goes up






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






28. Crops and crop residue






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






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






31. 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






32. Burning wood






33. Difference between high and low tide






34. Semi-permeable dams






35. Water conservation - jobs - energy -






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






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






38. Burning biomass






39. Burning rubbish/garbage






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






41. Replenish themselves or are continuously present






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






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






44. Bacteria ferments biomass with sugars






45. Accumulation of organic material by living things






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






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






48. Off shore wind is the most efficient






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






50. 3 factors that affect volatility
