Characteristics of the Sun

The sun has layers

The middle is called the core – it is 27,000,000 degrees!

The outer layer is the chromosphere

The layer under the chromosphere is the photosphere, where light and other forms of energy are released

Under the photosphere is the convective zone where heat is released

The layer above the core is the radiative zone

Slide 4

The sun is made up of gasses

The most abundant gas is Hydrogen

Hydrogen is undergoing fusion to make Helium, which releases a huge amount of energy

Forms of energy released include light, heat, and various rays, like X rays and gamma rays, which are forms of radiation
