ocr: MAGNETOSPHERE Around the Earth is a comet-like, fan-shaped tail - the magnetosphere. On the side of the Sun (the dayside) it extends to some 100,000 km and in the other direction (the nightside), due to: the influence of the solar wind, it extends millions of kilometres. Without a magnetic field life, as we know it, would be impossible on Earth; high-energy particles originating from the Sun would destroy every form of life on Earth. The magnetosphere forms the Van Allen Radiation belts, which capture these high-energy particles. When a magnetic storm reaches the magnetosphere, the electrons, ...
