Ch 26-1 The sun

  1. 1. The Sun 26.1 Energy From the Sun Forces in Balance Atmosphere Features
  2. 2. Energy From the Sun <ul><li>Sun Give of Electromagnetic Radiation = Energy that is given off in Waves </li></ul><ul><li>Ex. Ultraviolet Light = Sun Burn </li></ul><ul><li>Energy for the sun = Nuclear Fusion in the core… </li></ul><ul><li>Small nuclei combine with other small nuclei making a massive nuclei & releasing lots of energy </li></ul>
  3. 3. Fusion Reaction <ul><li>Deuterium-deuterium reactions - Two deuterium atoms combine to form a helium-3 atom and a neutron. </li></ul>
  4. 4. Radio Waves Visible Light X-rays Radiation Microwaves
  5. 5. Forces in Balance <ul><li>The sun is stable because of two forces </li></ul><ul><li>The pressure of nuclear fusion pushing outward </li></ul><ul><li>The force of gravity pulling inward </li></ul>
  6. 6. Atmosphere <ul><li>Sun’s Atmosphere is made up of 3 layer </li></ul><ul><li>Photosphere = Inner layer of atmosphere — </li></ul><ul><li>The visible surface of the sun — </li></ul><ul><li>Has a bubbly appearance called Granules </li></ul>
  7. 7. Chromosphere <ul><li>Chromosphere = Middle layer of atmosphere— </li></ul><ul><li>Name = sphere of color can be seen when photosphere is blocked </li></ul>
  8. 8. Corona <ul><li>Corona = Outer layer of atmosphere— </li></ul><ul><li>Gasses in layer a very hot 1million Kelvins— </li></ul><ul><li>Beginning of solar winds = charged particle that flow out from the Corona— </li></ul><ul><li>Earth magnetic field deflects cause the auroras </li></ul>                    
  9. 9. Features <ul><li>Sunspots = Areas of gas in the photosphere that are cooler than surrounding gases </li></ul><ul><li>Prominences = are huge loops of gas that erupt from sunspot regions </li></ul><ul><li>Solar Flares = a sudden release of energy from sun </li></ul>
