16.2 What is a star
Coronal streamer-A wisp-like stream of particles that gradually moves away from the Sun and becomes part of the solar wind.

16.2 What is a star
Coronal holes - are areas of the Sun's surface that are the source of open magnetic field lines that head way out into space.

16.2 What is a star
Photosphere - imaginary surface from which the solar light that we see appears to be emitted.

16.2 What is a star
Sunspot – temporary phenomena on the photosphere caused by magnetic activity which inhibits convection forming areas of reduced temperature.

16.2 What is a star
Chromosphere – An incandescent, transparent layer of gas, primarily hydrogen, several thousand miles in depth, lying above and surrounding the photosphere of a star, such as the sun, but distinctly separate from the corona.

16.2 What is a star
Filament – are formed in magnetic loops that hold relatively cool, dense gas suspended above the surface of the Sun.

16.2 What is a star
Corona hole – areas where the Sun's corona is darker, colder, and has lower-density plasma than average.

16.2 What is a star
Convective Zone – the range of radii in which energy is transported primarily by convection.

16.2 What is a star
Radiative Zone – In the radiation zone, energy is transported by radiation.

16.2 What is a star
Core – The core is the source of all the Sun's energy. The Sun's core has a very high temperature, more than 15 million degrees Kelvin, and the material in the core is very tightly packed or dense
