Sun's layers quick check

Answer 1

The Sun consists of several distinct layers, each with unique characteristics and functions. Here's a quick overview:

1. Core: The innermost layer, where nuclear fusion occurs, producing energy from hydrogen. Temperatures reach around 15 million degrees Celsius.

2. Radiative Zone: Surrounding the core, this layer transfers energy outward through radiation. It spans from the core to about 70% of the Sun's radius and can take millions of years for energy to pass through.

3. Convective Zone: Above the radiative zone, this layer facilitates energy transfer through convection. It is where hot plasma rises, cools, and sinks back. It extends from about 70% of the radius to the surface.

4. Photosphere: This is the visible surface of the Sun that we see. It has a temperature of about 5,500 degrees Celsius and is where sunspots can occur.

5. Chromosphere: Located above the photosphere, this layer is visible during solar eclipses and has a temperature of around 20,000 degrees Celsius. It can be seen as a red ring during an eclipse.

6. Corona: The outermost layer of the Sun's atmosphere, extending millions of kilometers into space. It is much hotter than the layers below it, with temperatures reaching between 1 to 3 million degrees Celsius. The corona is visible during a total solar eclipse.

Each layer plays a crucial role in the Sun's structure and the energy processes that sustain it.
