SOLAR SYSTEM

Detailed explanation-1: -The Core. The Sun’s core is the central region where nuclear reactions consume hydrogen to form helium. These reactions release the energy that ultimately leaves the surface as visible light. These reactions are highly sensitive to temperature and density.

Detailed explanation-2: -The core of the Sun is home to billions and billions of atoms of hydrogen, the lightest element in the universe. The immense pressure and heat pushes these atoms so close to one another that they squish together to create new, heavier atoms. This is called nuclear fusion.

Detailed explanation-3: -Inside the sun. The structure of the sun is made up of four layers. At the very center is the dense, hot core. Around the core lie two layers: a thick layer called the radiative zone and a thinner, cooler layer called the convective zone.

Detailed explanation-4: -The Sun’s interior isn’t solid like the interior of Earth. It is a ball of swirling, hot plasma that is held together by a balance of forces between gravity and pressure.
