Layers of the Sun Labeling Worksheet with diagram and definition table.

The image shows a "Layers of the Sun Labeling Worksheet" with two parts:

1. A diagram of the Sun with labeled blanks pointing to different layers and features.
2. A table titled "Sun Parts Definition Table", where students must define each part.

Below is the completed solution for both parts, based on standard solar science knowledge.

✔ Part 1: Labeling the Diagram

Using the word bank:
> Corona, Chromosphere, Photosphere, Prominence, Coronal Hole, Sunspots, Convection Zone, Flare, Subsurface flows, Radiative Zone, Core

Here’s how the diagram should be labeled (from innermost to outermost, following typical structure):

#### Inner Layers (from center outward):
- Core – The central region where nuclear fusion occurs.
- Radiative Zone – Surrounds the core; energy travels through radiation.
- Convection Zone – Outer layer of the interior where heat rises in convection currents.
- Photosphere – The visible "surface" of the Sun; where sunlight is emitted.
- Chromosphere – A thin layer above the photosphere; reddish during solar eclipses.
- Corona – The outermost atmosphere of the Sun; visible during total solar eclipses.

#### Surface Features (on or near the surface):
- Sunspots – Dark, cooler areas on the photosphere caused by magnetic activity.
- Prominence – Large loops of plasma extending from the chromosphere into the corona.
- Flare – Sudden burst of energy from the Sun’s surface, often associated with sunspots.
- Coronal Hole – Regions in the corona where the magnetic field opens out into space; source of high-speed solar wind.
- Subsurface flows – Plumes of gas moving beneath the photosphere (often seen as granulation).

> 📌 Note: On the diagram, the arrows point to various locations. Based on common worksheet layouts:
>
> - Top arrow → Corona
> - Middle-right → Chromosphere
> - Bottom-right → Photosphere
> - Center-left → Core
> - Inner ring around core → Radiative Zone
> - Outer ring before photosphere → Convection Zone
> - Surface spots → Sunspots
> - Loop-like feature → Prominence
> - Burst-like feature → Flare
> - Dark area in corona → Coronal Hole
> - Flow patterns below surface → Subsurface flows

✔ Part 2: Sun Parts Definition Table

| Part of the Sun | Definition |
|------------------------|----------|
| Chromosphere | The layer of the Sun's atmosphere above the photosphere, visible as a reddish glow during solar eclipses. |
| Convection Zone | The outer layer of the Sun’s interior where heat is transferred by convection currents. |
| Core | The central region of the Sun where nuclear fusion converts hydrogen into helium, releasing vast amounts of energy. |
| Corona | The outermost layer of the Sun's atmosphere, extending millions of kilometers into space; visible during a total solar eclipse. |
| Coronal Hole | A region in the Sun’s corona where the magnetic field lines open out into space, allowing solar wind to escape more easily. |
| Flare | A sudden, intense burst of radiation from the Sun’s surface, often occurring near sunspots. |
| Photosphere | The visible "surface" of the Sun; it emits most of the light we see. |
| Prominence | A large, bright loop of gas that extends from the Sun’s chromosphere into the corona. |
| Radiative Zone | The layer surrounding the core where energy moves outward via radiation. |
| Subsurface flows | Patterns of gas movement beneath the Sun’s surface, including convective cells and differential rotation. |
| Sunspots | Cooler, darker regions on the Sun’s surface caused by strong magnetic fields inhibiting convection. |

🔍 Summary of Key Concepts

- The Sun has three main internal layers: Core, Radiative Zone, and Convection Zone.
- The outer atmospheric layers are: Photosphere, Chromosphere, and Corona.
- Surface phenomena include sunspots, flares, prominences, and coronal holes.
- Subsurface flows help drive solar dynamics and influence solar activity cycles.
