SOLAR SYSTEM

Detailed explanation-1: -In the Sun’s core, nuclear fusion takes place. It produces the energy that reaches Earth. The fusion reactions convert hydrogen nuclei into helium nuclei.

Detailed explanation-2: -Answer and Explanation: The very high temperature and pressure in the sun’s core allows the nuclear reaction fusion to occur. Fusion is a nuclear reaction that occurs when two or more elements are squeezed together under extremely high temperature and pressure.

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 main fuels used in nuclear fusion are deuterium and tritium, both heavy isotopes of hydrogen. Deuterium constitutes a tiny fraction of natural hydrogen, only 0, 0153%, and can be extracted inexpensively from seawater. Tritium can be made from lithium, which is also abundant in nature.
