Atomic fusion is the process that causes the sun to emit energy, which in turn warms the Earth and keeps life there possible. Alternative
This is further explained below.
Generally, Because it is a main-sequence star, the Sun gets its energy from the fusing of hydrogen nuclei into helium via the process of nuclear fusion.
The Sun's core is responsible for the fusion of 500 million metric tons of hydrogen every single second.
The curve represents the nuclear binding energy. As seen in the previous image, the production of nuclei with masses up to iron-56 results in the release of energy.
In conclusion, Atomic fusion generates energy emissions from the sun that warm and sustains life on the Earth. Option A
