To determine the correct naming of the Sun's layers described in columns A, B, and C, we need to match the given characteristics (Position, Thickness, and Temperature) of each layer to their known scientific names.
Given Data:
- Position: Lowest, Middle, Outermost
- Thickness: [tex]\(100 \, \text{km}\)[/tex], [tex]\(2000 \, \text{km}\)[/tex], Millions of kilometers
- Temperature: [tex]\(5500 \, \text{K}\)[/tex], [tex]\(6000 \, \text{K} \, \text{to} \, 20000 \, \text{K}\)[/tex], [tex]\(2000000 \, \text{K}\)[/tex]
1. Layer A:
- Position: Lowest
- Thickness: [tex]\(100 \, \text{km}\)[/tex]
- Temperature: [tex]\(5500 \, \text{K}\)[/tex]
This description matches the Photosphere, which is the lowest layer of the Sun’s atmosphere and has a temperature around [tex]\(5500 \, \text{K}\)[/tex].
2. Layer B:
- Position: Middle
- Thickness: [tex]\(2000 \, \text{km}\)[/tex]
- Temperature: [tex]\(6000 \, \text{K} \, \text{to} \, 20000 \, \text{K}\)[/tex]
This description matches the Chromosphere, which lies above the Photosphere and has a temperature range from [tex]\(6000 \, \text{K}\)[/tex] to [tex]\(20000 \, \text{K}\)[/tex]. It is thicker than the Photosphere.
3. Layer C:
- Position: Outermost
- Thickness: Millions of kilometers
- Temperature: [tex]\(2000000 \, \text{K}\)[/tex]
This description matches the Corona, which is the outermost layer of the Sun’s atmosphere and has a temperature of a few million degrees Kelvin.
Based on these observations, the correct matching of the Sun's layers to the table columns is:
Column A: Photosphere
Column B: Chromosphere
Column C: Corona
Hence, the correct answer is:
A: Photosphere
B: Chromosphere
C: Corona
The option that corresponds to these names is:
A: Photosphere; B: Chromosphere; C: Corona
Therefore, the answer is:
4. A: Photosphere; B: Chromosphere; C: Corona
