The Layers of The Sun
This picture of the Sun's layers came from http://www.windows2universe.org/sun/Solar_interior/solar_furnace.html
The Core
The Sun's core is about 7,000 degrees Fahrenheit, and contains 40% of the Sun's mass and 10% of its volume.

The Radiative Zone
The Radiative Zone of the Sun is where energy is transported from the super hot inner layers to the cooler outer layers by photons, this layer contains about 85% of the Sun's radius.

The Convection Zone
The Convection Zone of the Sun is where hot gases sink and cooler gases rise, giving it the name of the convection zone. This the outermost layer of the Sun's interior.
The Photosphere
The Sun's Photosphere is the visible surface of the Sun, and is not a solid surface, but is about 60 miles thick. This layer of the Sun is about 5,500 degrees Fahrenheit.
The Chromosphere
The Sun's Chromosphere is about 1,200 to 1,800 miles thick, and is hard to see next to the bright photosphere, but can be easily seen during a total solar eclipse.

The Corona
The Sun's Corona is most easily visible during solar eclipse like the Chromosphere, and is millions of degrees Fahrenheit. The Corona is a million times less bright than the Photosphere.
What Are Sunspots?
Sunspots are dark spots that appear on the surface on the surface of the sun. They appear darker because they are cooler than the surround areas.
What Are Prominences?
Prominences are huge arches of glowing gas that extend outward from the sun’s surface. These prominences are caused by eruptions of gases on the Sun's surface.
What is a Flare?
A flare on the Sun is an explosion that occurs on the Sun's surface. Flares are caused by an explosion of magnetic energy in the Sun's atmosphere that gives off an extreme burst of brightness.

What is an Aurora?
An aurora is a natural electrical phenomenon characterized by the appearance of streamers of reddish or greenish light in the sky, usually near the northern or southern magnetic pole. Auroras are caused by Solar Flares and Coronal Mass Ejections.
