Educational diagram illustrating the internal and external layers of the Sun.

Let’s solve this step by step.

We are matching parts of the Sun to their descriptions. The diagram has arrows pointing to different layers or features, and we need to fill in each blank with the correct term from the word bank at the bottom.

The word bank includes:
- Chromosphere
- Core
- Convection Zone
- Corona
- Photosphere
- Radiative Zone

Now let’s go one description at a time:

1. “the outermost layer of the sun's atmosphere only visible during an eclipse”
→ This is the Corona. It’s the faint, glowing halo you see around the Sun during a total solar eclipse.

2. “the hottest part of the solar system the source of the sun's energy”
→ That’s the Core. All the nuclear fusion happens here — it’s super hot and makes all the Sun’s energy.

3. “heat from the core moves outward to the sun's surface in this zone”
→ After the core, heat travels through the Radiative Zone. Energy moves slowly here as radiation (like light bouncing around).

4. “a reddish glow around the sky, part of the sun's atmosphere”
→ That’s the Chromosphere. You can sometimes see it as a red rim during eclipses — it’s just above the photosphere.

5. “layer on the surface of the sun that gives off light”
→ That’s the Photosphere. This is what we normally think of as the “surface” of the Sun — it’s where sunlight comes from.

6. “areas of the sun both rise up and sink down which helps move heat from the core”
→ That’s the Convection Zone. Hot material rises, cools, then sinks — like boiling water — helping carry heat outward.

Let’s double-check:

- Outermost atmosphere → Corona ✔
- Hottest, energy source → Core ✔
- Heat moves outward via radiation → Radiative Zone ✔
- Reddish glow → Chromosphere ✔
- Surface layer giving off light → Photosphere ✔
- Rising/sinking areas moving heat → Convection Zone ✔

All match correctly!

Final Answer:
Top left box: Corona
Top right box: Core
Middle right box: Radiative Zone
Bottom left box: Chromosphere
Bottom middle box: Photosphere
Bottom right box: Convection Zone
