If you were to cross a large redwood tree, like for an example a sequoia, from the middle of the trunk you would first cross the annual rings, indicators of the trunk growth over the years, then after that you would cross the phloem, the ''piping'' of the tree responsible for the transport of water throughout the tree and in the end you would cross the tree's bark, the protective layer on surface of the trunk.
Answer: Beginning from the inside and moving towards outside the sun has six layers. Sun is the ultimate source of energy for all the living organisms on earth. The heat and light that comes out of the sun is through the various layers that is present in the sun.
1. Innermost core: It is the region from where the sun gets all the energy. Here hydrogen and helium is present. Due to high pressure of the surrounding layers hydrogen fuses into helium releasing high energy photons.
2. Radiative zone: The high energy photons are now transferred from core to radiative zone. Here the high energy photons are constantly absorbed and re-emitted. It takes millions and billions of years for these high energy particles to come out of this radiative zone.
3. Convective zone: The temperature of this region is quite cooler as compared to that of core and radiative zone. The plasma present in this region makes the magnetic field of the sun.
4. Photosphere: It is the region where sunspots are found. These are called by the magnetic field of sun.
5. Chromosphere: This region is red in color. It contains filaments of gas that rise up from the surface of the sun. This region is cooler than photosphere.
6. Corona: It is the outermost layer of sun and the temperature is much higher here. Many kinds of gaseous emissions takes place make the sun bright and hot.
