LAYERS OF THE SUN

CORE

• Nuclear fusion takes place here.
• Packed with plasma.
• Temperatures of 15,700,000 K.
• 12% of the suns radius.
• 10% of total mass.

RADIATIVE LAYER

• Allows heat transfer by gramma photons
• Temperature is 5,000,000 K
• 73% of radius

CONVECTION LAYER

• Temperature is 2,000,000 K
• 15% of Suns radius

PHOTOSPHERE

• The visible surface of the sun
• Temperature is 6,000 K

CHROMOSPHERE

• Beginning of the Suns atmosphere
• Temps increase to 20,000 K

CORONA

• Temp rises to around 2,000,000 K
• Divided into two regions
• The inner corona extends for millions of kilometers
• Outer region is known as solar winds and extend out further than earth

NUCLEAR FUSION

• In the core hydrogen is formed into helium
• This converts energy into light
