1. THE SUN

2. How does the Sun get its energy?
In the core
Hydrogen particles collide and form helium through fusion.
This process releases energy.

3. Layers of the Sun
CORE
Center of the Sun, very dense gas, 15 million degrees Celsius, fusion occurs

4. Layers of the Sun Radiative Zone and Convection Zone
Energy transfer from core to surface
NOT layers, just zones

5. Layers of the Sun Photosphere
Photons of light released, its what we can see!
Has bumpy texture; 5, 500 degrees C

6. Layers of the Sun Chromosphere: middle layer of Sun’s atmosphere
Corona: particles and energy that extends out from the Sun

7. The Sun
Sunspots: spots on the photosphere that are cooler than surrounding areas, still bright
11 year cycle
Evidence that Sun rotates – 27 days
Occur with solar storms

8. Flares: eruptions of hot gas from Sun’s surface near sunspots
Prominences: loops of glowing gas that extend into corona, magnetic fields connecting

10. Solar Wind: electrically charged particles that flow out in all directions from the corona
Can form auroras on earth

12. Questions Where does the Sun’s energy come from?
How are sunspots different from other areas of the photosphere?
What causes auroras to form?

13. Questions What is #1? What is #4? What is #5?
What layer can you only see during a solar eclipse?
What can cause electrical and radio disruptions on Earth?
