Question

the layer of the interior where the temperature drops from 7,000,000C to 2,000,000C is
A. core
B. radiation zone
C. convection zone

Answer 1

Within the composition of stars, there are a number of distinct zones with different regimes of behavior. In the case of the Sun, the temperature profile listed above equates to that of the radiation zone, where the temperature falls over 5 million degrees Celsius. Thus the answer is B. radiation zone.

Answer 2

Answer:

Radiation Zone.

Explanation:

This zone is place between the inner core and the outer convective zone. Its temperatures decay from 7 million to 2 million across this zone.

Through this layer, energy is transported to outside the stars, and involves radiative diffusion process. All these energy travels in form of photons, which you can imagine like energy packages that are transported in the electromagnetic waves.
