Question

How does the sun's photosphere affect earth?

Answer 1

The photosphere is the layer of the Sun where visible light is created.

Explanation:

There are different levels or regions in the makeup of the Sun and the workings of each region are quite different.

The photosphere is the top layer of the Sun and that is where nuclear reactions occur that generate visible light. Without that layer, we wouldn't see the Sun and there would be no visible light that would "light up" our planet.

(Of course, with sight being such an important part of the sensory organs of many different animals, humans included, our eyes would have evolved a way to sense wavelengths that were available!)
