Atmosphere: There are three regions that the atmosphere consists of; these are the photosphere, the chromospheres and the solar corona. The photosphere is the part of the sun we can see, it is the region that produces white light. The other regions, the chromospheres and the solar corona also produces white light, but the white light can only be seen when the photosphere is blacked out which this occurs in a solar eclipse. The sun produces electromagnetic radiation; this is in many types of radiation like radio, ultraviolet, X-ray and gamma rays. These all originate from different parts of the sun.

Solar Activities:The sun can release sudden energy bursts. The most frequently solar flares events are sudden, localized transient increase in brightness which active regions near sunspots. The large flares from the sun are X-ray flares this is know because they are the brightest and exceeds the rest of the other flares. The flare that the sun emits can sometimes reach as far as our atmosphere, this can be seen when the atmosphere glows also when the atmosphere glows also know as an aurora. Other event that takes place on the sun is coronal mass ejection, this is where a helmet streams into the solar corona, and there is 10,000,000,000,000 kilograms of material entering the solar winds. The coronal mass ejections are where the cool dense prominence material erupts outward into space. All of the flare and coronal mass ejections are believed to be driven by the energy released from the solar magnetic field. The sun activity is not consistent and the sunspot shows this because they are visible. The numbers of sunspots level are not consistent and tie in with the solar activity this varies with an 11 year period also know as the solar cycle. The sunspots are storms, which can be seen of the surface of the sun, they are called sunspots because they look like dark spots.
