1. What is the sun? What is the structure of the sun?
What features can you see on the sun?

2. The sun: No solid surface Big ball of gas 1/4Helium 3/4Hydrogen
1,000,000 times the volume of Earth
Largest object in our solar system
Medium size star

3. Layers of the sun Core Radiation Zone Convection Zone
Where sun produces energy
Radiation Zone
Electromagnetic radiation
Convection Zone
Outermost layer

4. The Sun’s Atmosphere Photosphere Chromosphere Corona “Crown”
Inner layer
What you can see
Chromosphere
Middle Layer

“Crown”

5. Solar Eruptions A sneeze from the sun
Similar to a volcano on Earth
Very Powerful
Effects can be felt on Earth

6. Solar Flares

7. Prominences Eruption of ribbon-like plasma
Extend in a loop as it traces the Sun's magnetic fields.
Tend to form over a timeframe of a day or several months

8. Prominence
Prominence are huge loops of gas that connect different parts of sunspot regions.
A solar flare is an explosion caused by hydrogen getting really hot, the gas shoots out into space causing a solar flare.
Sort of like an after shock of an earthquake

9. So what is the difference?
Prominence
A prominence looks like a ribbon of glowing gases and disappears in a few days or months.
Solar Flare
A solar flare is an explosive eruption of waves and particles that lasts for minutes or hours.
