By observing the motion of the solar surface, scientists can determine the wavelength and the frequencies of the individual waves and deduce information about the solar interior not obtainable by other means. From these studies we get a picture of the inside of the sun. All three parts describe a cross-sectional cut through the center of the Sun. The conditions in the sun are incredible. Ultra-high temperatures and densities.
Particles move around very fast and collide.
This is what allows nuclear Fusion to occur in the core. In the convective zone the electrons can combine with nuclei to make atoms. Energy is absorbed by atoms. The absorbed energy sets solar gas moving like water in a pot. We can visualize the upper interior as a boiling, seething sea of gas.
