Question

what is sun's thin layer called???​

Answer 1

Explanation:

Around the core lie two layers: a thick layer called the radiative zone and a thinner, cooler layer called the convective zone. Surrounding all of them is the sun's surface layer, known as the photosphere. Above this lies the sun's thin atmosphere, which is made up of the chromosphere and the corona.

Answer 2

Answer:

Chromosphere

Explanation:

The chromosphere extends for about 2,000 kilometers (1,200 miles) above the visible surface of the Sun. Compared to the radius of the Sun, which is nearly 700 thousand kilometers (more than 400 thousand miles), the chromosphere is a very thin layer.
