The Sun comprises of six layers: the core (fusion site), radiative zone (energy transfer via photons), convective zone (plasma currents), photosphere (visible surface), chromosphere (reddish layer during eclipses), and corona (million-degree outer atmosphere). Each layer plays a role in energy production and solar phenomena like sunspots.
