Other courses by me .Summary of Yojana for UPSC Mains 2019 Ancient History Crash Course Summary of History NCERT's titled 'Our Pasts- I, II, III Summary of History NCERT's titled Themes in Indian History- I, II, III
Q1- Which among them is true? The theme for World Meteorological Day 2019 is "The Sun, A. B. C. Both the Earth and the weather Sun spots are magnetic in nature, usually occur in pairs and are therefore known as Bipolar Magnetic Regions D. None

BOTH Our Sun is a huge ball of electrically-charged hot gas. This char ged gas moves, generating a powerful magnetic field. The Suns magnetic field goes through a cycle, called the solar cycle Every 11 years or so, the Sun's magnetic field completely flips.T his means that the Sun's north and south poles switch places. 1T hen it takes about another 11 years for the Sun's north and sou th poles to flip back again. The solar cycle affects activity on the surface of the Sun, sucha s sunspots which are caused by the Sun's magnetic fields. As th e magnetic fields change, so does the amount of activity on the Sun's surface.
