Question

1. which of the following layers of the sun has a reddish color due to its temperature?

corona
chromosphere
photosphere
atmosphere

Explanation:

The chromosphere is a layer of the sun's atmosphere. It is visible as a reddish - colored layer just above the photosphere. This reddish color is due to the presence of hydrogen gas in this layer. When hydrogen is heated, it emits light in the red part of the spectrum. The corona is the outermost layer of the sun's atmosphere and is usually only visible during a solar eclipse. The photosphere is the visible "surface" of the sun and has a yellow - white appearance. The term "atmosphere" is too general as it encompasses both the chromosphere and the corona.

Answer:

chromosphere
