Which of the following protects earths atmosphere from solar wind

Astronomers have formed their ideas about the layers of the sun by using theoretical models combined with known data.

The correct answer is:

using theoretical models combined with known data

Astronomers have formed their ideas about the layers of the sun primarily through theoretical models combined with known data. These models are developed based on our understanding of the laws of physics and known facts about the sun. Astronomers use data collected from various sources such as satellite observations, ground-based telescopes, and spacecraft missions to construct these models. By comparing the observations with the predictions of the theoretical models, scientists can refine their understanding of the layers of the sun and make more accurate predictions about its structure and behavior.
