The core

The core is where nuclear reactions consume hydrogen to form helium. They release energy that leaves the surface as visible light. Some characteristics are consists of about 70% Hydrogen, 28% Helium and 2% of metals such as iron. Other characteristics are its rotation, temperature, and radiation.

Radiative zone

Energy is primarily transported to this layer. Then energy travels through there. Some characteristics are it spins differently then some of the inner layers.

Convective Zone

It extends to the visible surface of the earth. Energy is also transported by this region. Some characteristics are it spins different from the inner layers.

The Photosphere

This is considered the surface of the sun.

The Chromospere

Which means crown is the outermost layer of gases that surround the sun. It is only seen during a solar eclipse.

The Corona

It extends to space and is mostly seen when there is a solar eclipse. Some characteristics are it is observable with a coronagraph.

Sunspots

Sunspots are dark spots that appear on the surface of the sun. They appear darker because they are cooler than the surround areas.

Prominence

A prominence is a large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape.

Flare

A flare is defined as a sudden, rapid, and intense variation in brightness.
