1. Solar Energy Earths energy balance

2. Suns 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. Fusion vs Fisson 4. Comparison of Fusion and Fission http://prezi.com/lzzpxsu-38kx/fusion-fission/ 5. The Suns Energy 6. The Suns Energy 7. Earths Magnetic Field The Earths 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 Suns Strongest energyA couple of good videos on earths magnetic field. http://www.youtube.com/watch?v=yEYy_nVC4L0 http://science.howstuffworks.com/environmental/planet-earth-videos-playlist.htm 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. During photosynthesis, 95% of the suns energy is NOT used by the plant Energy used in Photosynthesis 10. Energy Flow Through the Ecosystem Each transfer of energy results in a loss of energy through heat 11. Trophic (energy) Levels 90% of energy Is LOST as heat Between one trophic level and the next.
