Science Kids: All About the Sun

The video explores the Sun's role in our solar system, its formation, and its composition. It explains the Sun's layers, including the core, radiative zone, and convective zone, and describes the Sun's atmosphere, consisting of the photosphere, chromosphere, and corona. The video also covers the Sun's distance from Earth, its gravitational pull, and its rotation. It concludes with a discussion on the importance of harnessing solar energy.
