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 K & 6,000 to 20,000 K & [tex]$2,000,000$[/tex] K \\
\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 :

To identify the names of the Sun's atmospheric layers based on their position, thickness, and temperature, we must analyze the provided table and match these properties to our knowledge of the Sun's layers.

The Sun has several distinct layers, which are:

1. Photosphere: This is the lowest layer of the Sun's atmosphere and is characterized by being relatively thin (about 100 km thick), with a temperature round about 5,500 K.
2. Chromosphere: This is found above the photosphere, with a thickness of about 2000 km and a temperature range between 6000 K to 20,000 K.
3. Corona: This is the outermost layer, extending millions of kilometers and having a very high temperature of about 2,000,000 K.

Let’s align this information with the provided table:

- Column A:
- Position: Lowest
- Thickness: 100 km
- Temperature: 5,500 K
- Column B:
- Position: Middle
- Thickness: 2000 km
- Temperature: 6,000 to 20,000 K
- Column C:
- Position: Outermost
- Thickness: Millions of kilometers
- Temperature: 2,000,000 K

Matching these layers with the Sun’s layer characteristics, we get:

- Column A describes the Photosphere.
- Column B describes the Chromosphere.
- Column C describes the Corona.

Therefore, the correct names corresponding to the columns A, B, and C are:
- A: Photosphere
- B: Chromosphere
- C: Corona

Hence, the correct option is:
A: Photosphere; B: Chromosphere; C: Corona

This matches with the final answer: 4.

So, the names of the Sun's layers in columns A, B, and C respectively are Photosphere, Chromosphere, and Corona, confirming option 4 as the correct answer.
