Study Notes
Composition of the Sun
- Made up of approximately 91% Hydrogen and 8.9% Helium.
Layers of the Sun
-
Core:
- Composed of plasma, which is the fourth state of matter.
- Extremely high temperature, reaching around 27,000,000°C.
-
Radiative Zone:
- Extends about 300,000 km, accounting for 45% of the Sun's total radius.
- Temperature in this zone is approximately 7,000,000°C, facilitating energy transfer through radiation.
-
Convective Zone:
- Approximately 200,000 km thick, surrounding the radiative zone.
- In this layer, energy is transported through convection processes.
