Understanding the structure of the Sun, including its core, radiation zone, convection zone, photosphere, chromosphere, and outer features like sunspots, solar flares, and prominences.

Let's solve this step by step.

Part 1: Labeling the Diagram of the Sun

We are given a diagram of the Sun with numbered parts (1 to 6). We need to label them based on standard solar anatomy.

From left to right, top to bottom:

- 1 → Outermost layer of the atmosphere — Corona
- 2 → The visible surface of the Sun — Photosphere
- 3 → The inner layer where energy is transferred by radiation — Radiation Zone
- 4 → The outermost layer of the Sun’s interior — Convection Zone
- 5 → The central region where nuclear fusion occurs — Core
- 6 → The layer above the photosphere that has a reddish glow — Chromosphere

So the labels are:

1. Corona
2. Photosphere
3. Radiation Zone
4. Convection Zone
5. Core
6. Chromosphere

Part 2: Matching Vocabulary Terms

Now match each term in the left column with the correct description letter from the right column.

Let’s go through each one:

---

7. solar flare
→ Eruptions that occur when loops in sunspot regions suddenly connect
✔ f

8. core
→ The center of the sun
✔ h

9. chromosphere
→ The layer of the sun’s atmosphere that has a reddish glow
✔ b

10. sunspot
→ Areas of gas on the sun’s surface that are cooler than the gases around them
✔ d

11. corona
→ The layer of the sun’s atmosphere that looks like a halo during an eclipse
✔ c

12. nuclear fusion
→ The joining of hydrogen atoms to form helium
✔ j

13. photosphere
→ The layer of the sun’s atmosphere that gives off visible light
✔ a

14. solar wind
→ A stream of charged particles produced by the corona
✔ g

15. prominence
→ Reddish loops of gas that link parts of sunspot regions
✔ e

16. radiation zone
→ The layer of the sun’s interior where energy is transferred mainly by electromagnetic radiation
✔ k

17. convection zone
→ The outermost layer of the sun’s interior
✔ i
