THE SUN'S MANY LAYERS


Though it may seem that the Sun is jsut a big hot ball of gas, it is really made up of a substance in the fourth stage of matter, called plasma. This state of matter tends to occur when a large amount of energy causes it's own atoms to break.

Furthermore, the sun is composed of layers, like many other heavenly bodies. It's major layers (in order from outermost to inner most) consist of the corona, the transition region, the chromosphere, the photoshere, the convection zone, the radiation zone, and the core.

Layers
Maximum Temperature
Information
Corona 1.8 Million Deg. Farenheit This is the outermost layer of the sun. It is thin and faint, and extends millions of miles into outerspace.
Transition Region 1.8 Million Deg. Farenheit This is the transition area from the corona to the chromosphere.
Chromosphere 10,800 - 90,000 Deg. Farenheit This layer rises 1240 miles above the photosphere.
Photosphere 10,000 Deg. Farenheit This layer, considered to be the sun's surface, is 60 miles thick and so dense we can't see through it. Here is where the sun's energy is given off in the form of heat and light.
Covection Zone 2,000,000 Deg. Farenheit The gases in this zone under go violent churning motions (called convections or turbulence) which help to carry the sun's energy to the surface. Heat from the Radiation zone cools as it rises to this level.
Radiation Zone 3.6 Million Deg. Farenheit Energy from the core radiates through this zone dropping it's temperature.
Core 27 Million Deg. Farenheit Thermonuclear reactions take place here. They power the sun, while billions of tons of pressure fuse hydrogen into helium.
