My Sun Foldable

2 of 7

Corona

  • Atmosphere of the sun
  •  2-3 million degrees C
  • Coronal Mass Ejections --- CMEs are large eruptions of particles (can disrupt Earth satellites)
  • Solar flares erupt from the surface into the corona
  • Prominences are colder, denser parts suspended above the corona

​

3 of 7

Chromosphere

  • 6000 - 20,000 C
  • Seen as color during eclipse

​

4 of 7

Photosphere

  • 6000 C
  • Visible portion
  • Sunspots --- darker, cooler 4000 C
  • Sunspots are magnetically active portions of the sun
  • May be related to climate/weather patterns

​

5 of 7

Convective Zone

  • 2 million C
  • Hot matter from radiative zone creates convection currents (hot matter rises, cold matter sinks)

​

6 of 7

Radiative Zone

  • Over 2 million C
  • 70% of sun's radius
  • Energy from core travels haphazardly to the convective zone

7 of 7

Core

  • 15 million C
  • Nuclear fusion takes place
  • Hydrogen fuses into helium releasing energy (light, heat)
