SOLAR SYSTEM

Detailed explanation-1: -RADIATION ZONE. The energy produced in the sun’s core moves outward through the middle layer of the sun’s interior, the radiation zone. The radiation zone is a region of very tightly packed gas where energy is transferred mainly in the form of electromagnetic radiation.

Detailed explanation-2: -Answer and Explanation: The difference between the radiation zone and the convection zone is as follows: The radiation zone of the Sun is the interior region of the sun, or the core of the Sun, from where the energy is generated due to fusion. The convection zone is the outermost inner layer above the radiation zone.

Detailed explanation-3: -In the Sun, the region between the solar core at 0.2 of the Sun’s radius and the outer convection zone at 0.71 of the Sun’s radius is referred to as the radiation zone, although the core is also a radiative region.

Detailed explanation-4: -The convection zone is the outer-most layer of the solar interior. It extends from a depth of about 200, 000 km right up to the visible surface. At the base of the convection zone the temperature is about 2, 000, 000° C.
