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 \\

\end{tabular}

What are the names of the Sun's layers described in columns [tex]$A$[/tex], [tex]$B$[/tex], and [tex]$C$[/tex]?

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 :

To determine the names of the Sun's atmospheric layers described in columns \( A \), \( B \), and \( C \), we can match their characteristics with known information about the Sun's layers.

Let's analyze each column and their properties:

1. Column A:
- Position: Lowest
- Thickness: 100 km
- Temperature: 5,500 Kelvin

The layer that fits this description is the Photosphere. The Photosphere is the visible surface of the Sun, and it has a temperature of about 5,500 Kelvin and a thickness of approximately 100 km.

2. Column B:
- Position: Middle
- Thickness: 2000 km
- Temperature: 6,000 to 20,000 Kelvin

The layer that fits this description is the Chromosphere. The Chromosphere is located above the Photosphere, has a thickness of about 2,000 km, and its temperature ranges from 6,000 to 20,000 Kelvin.

3. Column C:
- Position: Outermost
- Thickness: Millions of kilometers
- Temperature: 2,000,000 Kelvin

The layer that fits this description is the Corona. The Corona is the outermost layer of the Sun's atmosphere, extends for millions of kilometers, and has a temperature of around 2,000,000 Kelvin.

By matching these characteristics, we conclude:

- A corresponds to the Photosphere
- B corresponds to the Chromosphere
- C corresponds to the Corona

Therefore, the correct answer is:
[tex]\[ \boxed{A: \text{Photosphere}; B: \text{Chromosphere}; C: \text{Corona}} \][/tex]
