To solve this problem, we need to identify the correct order of the Sun’s internal layers
from the center outward.
The three layers shown in the diagram are:
-
Core
-
Radiative Zone
-
Convection Zone
---
🔬 Scientific Explanation:
The Sun is structured in concentric layers. Energy generated in the center must travel outward through these layers before reaching the surface (photosphere) and being radiated into space.
1.
Core — This is the
innermost layer. It’s where nuclear fusion occurs — hydrogen atoms fuse to form helium, releasing enormous amounts of energy in the form of gamma rays and heat. Temperature here is about 15 million °C.
2.
Radiative Zone — Surrounding the core. In this zone, energy from the core travels outward
by radiation — photons bounce around for thousands to millions of years as they slowly make their way out.
3.
Convection Zone — The outermost layer of the Sun’s interior (before the atmosphere). Here, energy is transported
by convection — hot plasma rises, cools, then sinks back down in a cyclical motion, like boiling water.

✔ Correct Order (from center to outer edge):
From the innermost layer (pointed by the top line) to the outermost (pointed by the bottom line):
>
Top box → CORE
>
Middle box → RADIATIVE ZONE
>
Bottom box → CONVECTION ZONE
---
📝 Final Answer to Fill In:
- Top blank:
CORE
- Middle blank:
RADIATIVE ZONE
- Bottom blank:
CONVECTION ZONE
This matches the physical structure of the Sun and the direction of energy flow from the core outward.
