In the radiative zone, energy moves from atom to atom in the form of electromagnetic waves, or radiation. Energy produced in the core moves through this zone by convection, the transfer of energy by moving liquids or gases.
In the radiative zone of a star, energy is transferred through electromagnetic radiation (photons) as it travels from the core to the convective zone. In contrast, in the convective zone, energy is transferred by the physical movement of hot gas or plasma through convection currents.

The three main parts of the Sun are the core, radiative zone, and convective zone. The core is where nuclear fusion occurs, producing the Sun's energy. The radiative zone is where energy is transported by electromagnetic radiation, and the convective zone is where energy is transported by convection currents.
radiative layer
The Sun's radiative zone is located between the core and the convective zone, where energy is transferred outward primarily through radiation. In this zone, photons take a long time to move through due to scattering, often taking thousands to millions of years to reach the outer layers. In contrast, the convective zone, which lies above the radiative zone, transports energy through convection, where hot plasma rises, cools, and then sinks, creating a more efficient and quicker transfer of energy. This difference in energy transfer mechanisms leads to distinct behaviors in these two layers of the Sun.
From the Sun's core, energy moves through the radiative zone, across the tachocline (transition layer) to the convective zone, and then to the outer convective zone with its visible granulation.
In the Sun's radiative zone, energy is transferred through radiation, where photons are absorbed and re-emitted by particles, taking a long time—up to thousands of years—to reach the outer layers. In the convective zone, energy transfer occurs via convection, where hot plasma rises to the surface, cools, and then sinks, creating a continuous cycle that efficiently transports energy to the Sun’s surface. This combination of radiative and convective processes ensures that energy generated in the core eventually reaches the surface, where it can radiate into space.
Energy from the core of the sun is transmitted through a process called radiative and convective heat transfer. In the radiative zone, energy is transported by photons through radiation. In the convective zone, energy is carried by circulating currents of hot plasma rising and cooler plasma sinking, a process known as convection. This energy eventually reaches the photosphere, where it is emitted as sunlight.
The radiative zone of the sun moves heat energy through radiation from the core to the convective zone. This zone transports heat through electromagnetic radiation as photons bounce around, transferring energy outward.
In the radiative zone of the sun, energy moves through the transfer of photons. Photons, which are massless particles of light, are created through nuclear fusion in the sun's core and gradually travel through the radiative zone, bouncing off particles in a zig-zag pattern until they reach the convective zone.
The interior layers of a star, from innermost to outermost, are the core, radiative zone, and convective zone. The core is where nuclear fusion occurs, generating the star's energy. The radiative zone is where energy is transported through radiation, while the convective zone is where energy is transported through the movement of gas.
The convective zone,energy is transferred much faster that it is in the radiative zone.
