Question

What is the middle layer of the sun’s atmosphere ?

Answer 1

Hint: The Sun is the central star of our Solar System. The sun is made up of six layers, of which three layers are called the inner layers and three are called the outer layers.The photosphere, chromosphere, and corona which are the outer layers of the sun, are the three layers that make up the sun's atmosphere.

Complete answer:
The Chromosphere is the middle layer of the atmosphere of the sun. It measures $3000$ to $5000$ kilometres in depth. This layer of the sun’s atmosphere has a rosy red colour and can be seen only during the eclipses. The radiation from the much lighter photosphere washes away the chromosphere, making it impossible to see without special equipment.

The chromosphere is located directly above the photosphere and below the solar transition zone. The Chromosphere is an irregular layer with a temperature range of ${6000^ \circ }C$ to ${20000^ \circ }C$. The hydrogen produces a reddish-coloured light at this temperature. Balmer H-alpha emission is the name for this phenomenon.

The Chromosphere comprises of two layers which are:
-The Upper Chromosphere - This is near the Corona
-The Lower Chromosphere - This is near the Photosphere.

Note: Stars other than the Sun have been seen to have chromospheres. The Sun's chromosphere has been difficult to study and decode, thought experiments using the electromagnetic spectrum are continuing.The sun's energy, which has bubbled up from the sun's inner layers, is sensed as sunlight in the outer layers.
