The sun is made of plasma. It has three layers of interior which are the core, radiation zone, and the convection zone.
The core-produces the a huge amout of the Sun's energy, which comes from nuclear fusion. In the process of nuclear fusion, hydrogen atoms fuse to form helium.
There are three layers of the Sun's atmosphere which are the photosphere, chromosphere, and the corona.
The photospheregives off visible light.
The chromosphere-gives the color of the sun. It causes the redish glow at the beginning of a solar eclipse.
The corona-sends out a stream of electrically charged particles called solar winds. Outer most layer
The sun also has features such as sunspots, prominences, and solar flares.
Sunspots- are darkers, cooler regions on the sun.
Prominences- Particles from the sun which explode and connect at sunspots forming a loop
Solar flares- are bigger explosions of energy from prominences.
