The energy produced by the sun is as a result of nuclear reactions which produces large amounts of energy.

What are chemical reactions?

Chemical reactions are reactions which occur as a result of a rearrangement of atoms of elements to form new combinations of substances known as compounds.

Since chemical reactions which have relatively short lifespans, scientist would have assumed that the sun is very young.

However, nuclear reactions have been proven to be the means by which the sun produces its energy.

Nuclear reactions release large amounts of energy and have relatively long lifespans.

Therefore, the energy produced by the sun is as a result of nuclear reactions.
