Step 1: The Sun's layers are organized from innermost to outermost.
The first layer is the core. • The core is the densest and hottest part of the Sun, where nuclear fusion occurs. It has a radius of about 174,000 kilometers (108,000 miles).
Step 2: The next layer after the core is the radiative zone.
• The radiative zone extends from the edge of the core to about 70% of the Sun's radius. In this layer, energy travels outward primarily in the form of photons, which can take a long time to pass through due to frequent collisions with atoms.
Final Answer
The seven layers of the Sun, starting from the innermost core, are: core, radiative zone, convective zone, photosphere, chromosphere, and solar corona.
