I. Layers of the SunA. The Core: The center of the sun
where fusion takes place.B. Radiation zone: energy flows from
core.C. Convection zone: energy circles
back toward core and is then pushed back out by energy coming from radiation zone.

II. Parts of the Sun
A. Sunspots: Cool areas around the sun which are not permanent.1. Caused by Magnetic Fields.2. High numbers occur every 11 years.3. Occur in pairs.4. When 2 sunspots come together, prominences and flares are produced.

II. Parts of the Sun
A. Prominences: Huge arching columns of gas.

III. Characteristics of the Sun
A. 99% of all the matter in our solar system is in the sun.
B. The sun is the center of the solar system.C. The sun is a main-sequence star. D. The sun produces energy by fusion.E. 75% Hydrogen and 25% Helium fuse in the
core.F. Fusing means two atoms combine to form
a heavier atom.

IV. Interesting Facts
A. The sun is a G2 star.B. The temperature of the core is 15.6 million
Kelvin.C. The sun is approximately 4.5 billion years
old.D. The sun emits a low-density stream of
charged particles known as the solar wind.E. Our sun is unique, not part of a binary
system, 2 stars orbiting each other.
