Study Notes
Layers of the Sun
- Core: The innermost layer where nuclear fusion occurs, producing energy that powers the Sun.
- Radiative Zone: The layer surrounding the core, where energy is transferred outward through radiation; it takes millions of years for energy to pass through this zone.
- Convection Zone: The outer layer of the Sun’s interior, characterized by convective currents that transport energy to the surface; hot plasma rises, cools, and then sinks.
- Photosphere: The visible surface of the Sun that emits light; it has a temperature of approximately 5,500 degrees Celsius and is where sunspots occur.
- Chromosphere: Located above the photosphere, this layer is seen during solar eclipses as a reddish glow and has a temperature range of about 4,500 to 20,000 degrees Celsius.
- Transition Region: A thin layer between the chromosphere and corona where temperature rapidly increases; plays a role in heating the solar corona.
- Corona: The outermost layer of the Sun's atmosphere, extending millions of kilometers into space; characterized by high temperatures (up to 2 million degrees Celsius) and visible during total solar eclipses.
