Sun is hot circle.
It is made out of minerals , lavas and volcanoes.
It has everything the hot and cold amount to control the universe.
Perhaps these are formed with ice, clouds, gas and they are made with water.
Sun is leading the gases of earth to give light.
It is natural leading.
It is eternal leading
Sometimes it comes with thunderstorm.
Above the sky, cloud took the hot gas and brought the fire as electricity .
It has created rainbow too.
Wonder of universe has brought good journey of nature.
So the sun is the great source of volcanoes and mineral.
