Answer: 1. The corona is in the outer layer of the Sun's atmosphere—far from its surface. Yet the corona is hundreds of times hotter than the Sun's surface. ... In the corona, the heat bombs explode and release their energy as heat. But astronomers think that this is only one of many ways in which the corona is heated. Our Sun is surrounded by a jacket of gases called an atmosphere. The corona is the outermost part of the Sun's atmosphere. The corona is usually hidden by the bright light of the Sun's surface. ... During a total solar eclipse, the moon passes between Earth and the Sun. 2. The chromosphere is above the photosphere, the visible "surface" of the Sun. It lies below the solar corona, the Sun's upper atmosphere, which extends many thousands of kilometers above the chromosphere into space. The plasma (electrically charged gas) in the chromosphere has a very low density. Chromosphere is a reddish and glowing layer of gas above a star's (or Sun's) photosphere. It is actually the transition between corona and the photosphere. Out of the three layers of the Sun's atmosphere, chromosphere is the second one (with photosphere being the first layer and corona as the third) 3. The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that. 4. The convection zone is the outer-most layer of the solar interior. It extends from a depth of about 200,000 km right up to the visible surface. At the base of the convection zone the temperature is about 2,000,000° C. Convection zone: This layer of the sun is above the radiative zone and is the outermost layer of the Sun's interior. It stretches from as deep as around 200,000 kilometers right up to the visible surface. ... Energy moves towards the Sun's surface through convection currents of heated and cooled gas. 5. The Sun's radiative zone is the section of the solar interior between the innermost core and the outer convective zone. In the radiative zone, energy generated by nuclear fusion in the core moves outward as electromagnetic radiation. In other words, the energy is conveyed by photons. This is the zone immediately next to the core, which extends out to about 0.7 solar radii. There is no thermal convection in this layer, but solar material in this layer is hot and dense enough that thermal radiation is all that is needed to transfer the intense heat generated in the core outward. 6. The Sun's central core is plasma with a temperature of around 27 million C . At such high temperatures hydrogen combines to form helium by nuclear fusion, a process that releases vast amounts of energy. This energy moves outward, towards the outer layers of the Sun. The core is the Sun's middle region where energy is generated by thermonuclear reactions, which create extreme temperatures of about 15 million degrees Celsius. These nuclear reactions use hydrogen to produce helium. brainliest?
