Taden has found a table of the atmospheric layers of the Sun. However, he can't make out the names of the layers in the chart.

\begin{tabular}{|l|l|l|l|}
\hline
& \multicolumn{1}{|c|}{ A } & \multicolumn{1}{c|}{ B } & \multicolumn{1}{c|}{ C } \\
\hline
Position & Lowest & Middle & Outermost \\
\hline
Thickness & 100 km & 2000 km & Millions of kilometers \\
\hline
Temperature & 5,500 & 6,000 to 20,000 & [tex]$2,000,000$[/tex] \\
\hline
\end{tabular}

What are the names of the Sun's layers described in columns A, B, and C?

A. Corona; B. Photosphere; C. Chromosphere
B. Core; B. Chromosphere; C. Photosphere
C. Chromosphere; B. Corona; C. Core
D. Photosphere; B. Chromosphere; C. Corona



Answer :

Sure, let's walk through the details of the Sun's layers based on the given table:

### Position of Layers:
1. Lowest Layer (Column A)
2. Middle Layer (Column B)
3. Outermost Layer (Column C)

### Thickness:
1. Lowest Layer: 100 km (Column A)
2. Middle Layer: 2000 km (Column B)
3. Outermost Layer: Millions of kilometers (Column C)

### Temperature:
1. Lowest Layer: 5,500 K (Column A)
2. Middle Layer: 6,000 to 20,000 K (Column B)
3. Outermost Layer: 2,000,000 K (Column C)

#### Analysis of the Layers:
1. Photosphere:
- Position: Lowest visible layer.
- Thickness: Approximately 100 km.
- Temperature: Around 5,500 K.

2. Chromosphere:
- Position: Middle layer above the Photosphere.
- Thickness: Approximately 2,000 km.
- Temperature: Ranges from 6,000 K to 20,000 K.

3. Corona:
- Position: Outermost layer.
- Thickness: Extends for millions of kilometers.
- Temperature: Around 2,000,000 K.

### Matching the Layers to Columns A, B, and C:
- Column A:
- Position: Lowest
- Thickness: 100 km
- Temperature: 5,500 K
- Name: Photosphere

- Column B:
- Position: Middle
- Thickness: 2000 km
- Temperature: 6,000 to 20,000 K
- Name: Chromosphere

- Column C:
- Position: Outermost
- Thickness: Millions of kilometers
- Temperature: 2,000,000 K
- Name: Corona

### Conclusion:
Based on the analysis, the names of the layers described in columns A, B, and C are:
- A: Photosphere
- B: Chromosphere
- C: Corona

Thus, the correct answer is:
A: Photosphere; B: Chromosphere; C: Corona.
