Layers of the Sun worksheet for students to label using provided terms.

Let’s solve this step by step.

We are labeling the layers of the Sun from the inside out, using the word bank:

Word Bank:
- chromosphere
- convection zone
- core
- corona
- photosphere
- radiative zone
- transition zone

First, let’s recall the order of the Sun’s layers — starting from the center and going outward:

1. Core – This is the very center, where nuclear fusion happens. It’s the hottest part.
2. Radiative Zone – Energy moves outward here through radiation (like light bouncing around).
3. Convection Zone – Hot plasma rises and cooler plasma sinks, like boiling water.
4. Photosphere – The “surface” we see when we look at the Sun. It’s the visible layer.
5. Chromosphere – A thin red layer above the photosphere, only visible during eclipses.
6. Transition Zone – A very thin region between the chromosphere and corona where temperature jumps up fast.
7. Corona – The outermost atmosphere, super hot but very thin, seen as a halo during total solar eclipses.

Now, looking at the diagram:

There are 7 blank lines pointing to different parts of the Sun cross-section.

Starting from the CENTER and moving OUTWARD:

→ The innermost circle = core

→ Next ring out = radiative zone

→ Next ring = convection zone

→ Then the next thin layer just below the surface = photosphere

→ Above that, a slightly thicker layer with spikes = chromosphere

→ Between chromosphere and corona = transition zone (very thin)

→ Outermost spiky halo = corona

But wait — in many diagrams, especially simplified ones, the transition zone might not be labeled separately or may be grouped. Let’s check how many labels there are: 7 blanks → matches our 7 terms.

Looking at the arrows:

Top right side (pointing to outer layers):

- Top arrow → points to the very outer edge/spikes → corona
- Second arrow down → points to the layer just inside corona → likely transition zone
- Third arrow → points to the reddish-looking layer under that → chromosphere

Bottom left side (pointing to inner layers):

- Bottom-most arrow → points to the center → core
- Next up → points to the middle gray ring → radiative zone
- Next → points to the lighter gray ring outside that → convection zone
- Top one on bottom left → points to the bright “surface” layer → photosphere

Wait — let’s match each line carefully based on typical textbook diagrams.

Actually, let’s list the layers again in order from center to edge:

1. Core
2. Radiative Zone
3. Convection Zone
4. Photosphere
5. Chromosphere
6. Transition Zone
7. Corona

In the diagram, the arrows point to:

From center outward:

- Innermost dot → core
- First ring around it → radiative zone
- Second ring → convection zone
- Thin line just before the “spikes” start → photosphere
- Then the first spiky layer → chromosphere
- Between chromosphere and full corona → transition zone
- Outermost spikes → corona

So now assign each blank box accordingly.

Assuming the boxes are arranged as follows (based on common layout):

Right side (top to bottom):

Box 1 → points to outermost → corona
Box 2 → points to layer just inside → transition zone
Box 3 → points to next layer inward → chromosphere

Left side (bottom to top):

Box 4 → points to center → core
Box 5 → points to first ring → radiative zone
Box 6 → points to second ring → convection zone
Box 7 → points to surface layer → photosphere

Yes — that makes sense.

Final Answer:

Label the boxes as follows:

Top right box (outermost): corona
Middle right box: transition zone
Bottom right box: chromosphere
Bottom left box (center): core
Next up on left: radiative zone
Next up: convection zone
Top left box (surface): photosphere

Final Answer:
From top to bottom on the right side:
1. corona
2. transition zone
3. chromosphere

From bottom to top on the left side:
4. core
5. radiative zone
6. convection zone
7. photosphere
