The Sun Section 24.2 Pg

The Sun  The sun is similar to most of the other stars in our galaxy  Large ball of gas made mostly of hydrogen and helium held together by gravity  Middle-aged yellow star

The layers of the sun  Core: center of the sun  Radiative zone: very dense region  Convection zone: where sun circulates energy  Photosphere: what we know as the surface of the sun  Chromosphere: see this region of sun’s atmosphere during a solar eclipse  Corona: outer atmosphere of the sun

Layers of the Sun

Surface Features of the Sun  Sunspots mark cooler areas on the sun’s surface; related to changes in the magnetic properties of the sun.  Solar Flares are giant storms on the surface of the sun. Particles from the solar flares interact with earth’s upper atmosphere called auroras.
