Describe the process occurring in the Sun’s core

The proton-proton fusion process that is the source of energy from the Sun. The energy from the Sun - both heat and light energy - originates from a nuclear fusion process that is occurring inside the core of the Sun. The specific type of fusion that occurs inside of the Sun is known as proton-proton fusion.

Explanation:

Have a great day everyone :)

This is what happens to the hydrogen gas in the core of the Sun. It gets squeezed together so tightly that four hydrogen nuclei combine to form one helium atom.

^This is called nuclear fusion. while this is happening some of the mass of the hydrogen atoms are made into energy in the form of light.
