SOLAR SYSTEM

Detailed explanation-1: -The photosphere is the lowest layer of the sun’s atmosphere-the innermost layer we can observe directly. The term photosphere means “sphere of light” and is the layer where most of the sun’s energy is emitted. It takes about eight minutes for sunlight from the photosphere to reach Earth.

Detailed explanation-2: -the corona-the outermost, hot shell of the atmosphere. the chromosphere-a transparent layer between the corona and the photosphere. the photosphere-the visible “surface” of the Sun.

Detailed explanation-3: -The lower region of the Sun’s atmosphere is called the chromosphere. It was named after the Greek root chroma (meaning color). The chromosphere appears bright red because the hydrogen in the Sun emits a reddish-colored light at high temperatures.
