HPU NCS2200 Sun earth energy transfer lecture

  1. 1. Solar Energy Earth’s energy balance
  2. 2. Sun’s Energy  Produced by Nuclear Fusion  FUSION = two atoms coming together  This process produces massive energy  Only occurs spontaneously on the Sun  Fission = atoms put out particles spontaneously  This process produces much less energy than Fusion  We use the fission process in nuclear power plants.
  3. 3. Fusion vs Fisson
  4. 4. Comparison of Fusion and Fission  http://prezi.com/lzzpxsu-38kx/fusion-fission/
  5. 5. The Sun’s Energy
  6. 6. The Sun’s Energy
  7. 7. Earth’s Magnetic Field The Earth’s Magnetic Field is created by the movement of electrical energy in the molten core within the earth. The Magnetic field protects us from much of the Sun’s Strongest energyA couple of good videos on earth’s magnetic field. http://www.youtube.com/watch?v=yEYy_nVC4L0 http://science.howstuffworks.com/environmental/planet-earth-videos-playlist.htm
  8. 8. Radiation is the transfer of energy across space and in the atmosphere Convecti on is the transfer of energy through a fluid. Air is a fluid Conduction is the transfer of energy through a solid material. How is energy transferred in the atmosphere? A Fluid is Anything That flows it includes Both air and liquids
  9. 9. During photosynthesis, 95% of the sun’s energy is NOT used by the plant Energy used in Photosynthesis
  10. 10. Energy Flow Through the Ecosystem Each transfer of energy results in a loss of energy through heat
  11. 11. Trophic (energy) Levels 90% of energy Is LOST as heat Between one trophic level and the next.
