Detailed explanation-1: -The Sun’s interior domain includes the core, the radiative layer, and the convective layer (Figure 2–1). The core is the source of the Sun’s energy, the site of thermonuclear fusion.

Detailed explanation-2: -In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.

Detailed explanation-3: -Experimental and theoretical data show that the main source of the earth’s energy, which is the prime cause of endogenic and tectonic processes, is fusion reactions that take place in the planet’s inner core, which consists of metal hydrides.

Detailed explanation-4: -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-5: -Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.
