What are the layers of the Sun, starting from the center and moving outward?



A. Core, convective zone, radiative zone, and photosphere

B. Core, radiative zone, convective zone, and photosphere

C. Photosphere, convective zone, radiative zone, and core

D. Radiative zone, convective zone, core, and photosphere

Answer :

Final answer:

The Sun has several layers that include the core, radiative zone, convective zone, and photosphere. The core is where nuclear fusion happens, while the other layers facilitate the transfer of energy to the surface. The correct order from the center to the outside is core, radiative zone, convective zone, and photosphere.


Explanation:

Identifying the Layers of the Sun

The Sun is structured in several layers, each playing a critical role in its function and characteristics. Starting from the center and moving outward, the layers of the Sun are as follows:

  1. Core: This is the innermost layer where nuclear fusion occurs, producing energy that powers the Sun.
  2. Radiative Zone: Above the core, energy produced in the core travels slowly through this zone by radiation.
  3. Convective Zone: In this layer, energy is transferred by convection currents, with hot plasma rising and cooler plasma sinking.
  4. Photosphere: This is the visible surface of the Sun that we see. It emits the light and heat that reaches Earth.

Thus, the correct order of the layers, from the center outward, is the core, radiative zone, convective zone, and photosphere.
