The Sun
By: Ryan Swanson
Layers of the Sun
Below is a graph of the layers of the sun. There are seven layers. The Corona, the Chromosphere, the Photosphere, the Subsurface flows, the Convection zone, the Radiative zone, and the Inner core. Temperature is around the same throughout all of the layers, around 5700 K. All of the inner layers are mainly liquid metal alloys. the outside layers are the layers that reflect light all of the way to earth.
Sunspots
Below is a picture of a Sunspot. Sunspots are large areas of the sun that are significantly cooler than the surrounding areas. this causes them to get darker than the rest of the sun.
Prominences
Below is a picture of a prominence. Prominences are large looped shaped figures that stick out from the sun. They are composed of super hot ionized gases, and are almost always bigger than the earth.
Flares
Below is a picture of a flare. A solar flare is a large eruption of energy on the suns surface causing large bands of plasma to expand from the sun. one blast is equivalent to around 160000000000 megatons of TNT.
Auroras
Below is a picture of an Aurora. An aurora is a large light display that usually happens in polar regions, One occurs whenever the magnetosphere is disturbed by solar winds. This causes beautiful lights in the sky.
