Which layer exists immediately above the photosphere before reaching the corona?
Answer
Chromosphere
The Sun's atmosphere is stratified into several distinct layers extending outward from the visible surface. Immediately above the photosphere, the layer where visible light escapes, lies the Chromosphere. Following the Chromosphere, the Sun extends into the vast and tenuous Corona, which stretches for millions of kilometers. These layers represent an outward progression into regions of lower density, although paradoxically, the temperature dramatically increases as one moves into the corona, reaching millions of degrees Fahrenheit.
