The Sun is a massive celestial body that radiates vast amounts of energy into space, providing light, heat, and other forms of electromagnetic Blank 1 Question 21 radiationrepulsiontransmissiongauge to the solar system. This energy originates from the process of fusion that occurs in the Sun's core. At the core, temperatures and pressures are so extreme that hydrogen nuclei fuse together to form helium nuclei, releasing immense amounts of energy in the process. This energy then travels through the Sun's layers via a process known as Blank 2 Question 21 radiative transportgravitational transportconvective transportconductive transport . As energy generated in the core moves outward, it passes through the radiative zone, where it is carried by electromagnetic particle ' Blank 3 Question 21 pionpositronphotonphonon ' through a series of absorption and emission processes. Eventually, the energy reaches the convective zone, where it is transported by the movement of hot plasma through convection currents. Once the energy reaches the Sun's surface, it is emitted into space in the form of solar radiation. The Sun emits radiation across the Blank 4 Question 21 partial decoherent spectrumwide celestial spectrumentire electromagnetic spectrumsolar variable spectrum , from radio waves to gamma rays, with the majority of theThe
