The correct answer is: releases energy that warms Earth.
Nuclear fusion is the process that powers the Sun and other stars. It occurs when two atomic nuclei join together to form a heavier nucleus, releasing a large amount of energy in the process. This energy is in the form of electromagnetic radiation, including visible light, which warms the Earth and makes life on our planet possible. The Sun's nuclear fusion reactions continuously release huge amounts of energy, which is then radiated out into space and eventually reaches Earth. This energy is essential for providing warmth and light, supporting the growth of plants, driving weather patterns, and sustaining life on Earth.
