What two energy transport mechanisms in order from outside the core to surface are found sun?

1. Radiative transport: This occurs in the innermost layers of the Sun, extending outward from the core to about 70% of the Sun's radius. Here, energy is carried by photons (light particles) that are constantly absorbed and re-emitted by the dense, ionized gas. This process is slow, as photons can take millions of years to travel this distance due to the frequent collisions and scattering.

2. Convective transport: This occurs in the outer layers of the Sun, extending from about 70% of the Sun's radius to the surface. Here, the energy is transported by rising hot gas (plasma) and sinking cooler gas in a process called convection. This is more efficient than radiative transport and allows for a much faster transfer of energy. This process is visible as the granulation observed on the Sun's surface.
