The suns warmth makes life on Earth possible. But our home star can also be dangerous flaring up and ejecting huge masses of the hot material that can travel across space to disrupt earths neighborhood.
With in the body of the sun, currents of hot plasma circulate in an immense system called the great conveyor belt. Each of the belts two branches north and south takes about 40 earth years to complete it.
In this completion process the due to the change in the polarity many storms are formed on the surface of the sun which are called as the solar storms and these release a lot of heat radiation which reach earth.
These Sun storms are the final level of the sun to change its poles.
