Chapter 14 Section 2 Notes: The Sun The sun produces energy through nuclear fusion. In the process of nuclear fusion‚ two atomic nuclei combine‚ forming a larger‚ more massive nucleus and releasing energy. Within the sun‚ hydrogen atoms join together to form helium. Such conditions exist in the sun’s core‚ or central region. The sun’s interior consists of the core‚ the radiation zone‚ and the convection zone. The sun’s energy is produced in its central core. The radiation zone is a region

live on a small planet in a tiny part of a vast universe. "This part of the universe is called the solar system‚ and is dominated by a single brilliant star-the sun." (Skywatching 230) The solar system is the earth ’s neighbourhood and the planets Mercury‚ Venus‚ Mars‚ Jupiter‚ Saturn‚ Uranus‚ Neptune and Pluto are the Earth ’s neighbours. They all have the same stars in the sky and orbit the same sun. Scientists believe the solar system began about 5 billion years ago‚ perhaps when a nearby star
