Not all the details of solar activity are known yet. The full solar cycle is really a 22-year cycle, since every 11 years (on average), the magnetic field flips; therefore the full cycle is 22 years (again, on average), since that's the time it takes to get back to its previous position.
Wikipedia says: "The basic causes of the solar variability and solar cycles are still under debate, ..." For more details, read the Wikipedia article on "Solar cycle".
Solar flares and prominences occur in 11-year cycles because of the Sun's magnetic field. This is known as the solar cycle, which is caused by the changing magnetic properties of the Sun. The cycle is driven by the Sun's internal dynamo mechanism, with peaks and valleys in solar activity occurring roughly every 11 years.
Solar flares, spicules, and prominences are driven by the Sun's complex magnetic field and its dynamic plasma. Solar flares occur when magnetic energy is released suddenly, causing explosive bursts of radiation. Spicules are jet-like structures formed by the interaction of magnetic fields with solar plasma, while prominences are large, loop-like structures of cooler plasma suspended in the Sun's atmosphere, often anchored to magnetic regions. These phenomena are all manifestations of the Sun's magnetic activity and the behavior of its ionized gases.
Oversimplified analogy: the solar wind is a near continuous fairly gentle outflow of gas from the sun in all directions, a solar flare is a giant hurricane force gust blown suddenly away from the sun in one single direction.
Although the cause of flares is not completely understood, they are known to be associated with the magnetic field of the Sun. One favored explanation is that they occur when magnetic fields in the Sun pointing in opposite directions interact strongly with each other. Such a situation can be brought about by the churning motion of solar material near the surface, and is more likely during periods of the active sun. Thus, there typically is a correlation between the frequency of flares and the number of sunspots.
Prominences are large, bright features extending outward from the Sun's surface, while solar flares are sudden, intense bursts of energy. The corona is the Sun's outer atmosphere, solar wind is a stream of charged particles flowing from the Sun, chromospheres are the middle layer of the Sun's atmosphere, and photospheres are the Sun's visible surface. Collectively, these components make up the dynamic system of the Sun's structure and activity.
Solar flares, coronal mass ejections (CMEs), and solar prominences are some of the most explosive events to occur on the sun. Solar flares are intense bursts of radiation, while CMEs release colossal amounts of solar material into space. Solar prominences are large loops of plasma extending from the sun's surface.
The layer of the sun's atmosphere responsible for flares, spicules, and prominences is the chromosphere. This layer lies above the photosphere and below the corona. It is where these solar phenomena occur due to the intense magnetic activity in the region.

Both solar flares and solar prominences are magnetic disturbances that occur on the Sun's surface. They both involve the release of a large amount of energy in the form of electromagnetic radiation. Solar flares and prominences are often associated with sunspots and can have significant impacts on space weather.

The solar surface is known as the photosphere, where the temperature is around 5,500 degrees Celsius. It emits visible light and is the layer from which sunlight is emitted. Sunspots, solar flares, and prominences are all phenomena that occur on the solar surface.

The colored layer of the sun is known as the chromosphere. It is located above the sun's visible surface (photosphere) and is characterized by its reddish coloration. The chromosphere is also where solar prominences and solar flares occur.
The sun spins faster at the equator then at the poles, this causes a difference in magnetic fields. Once one is looped, the temperature of the area will decrease, causing a sun spotSunspots are caused by the intense magnetic field of the sun, they usually occur the most during the high peak of the solar cycle.
