Effect of solar wind on earth

                                  Effect of solar wind on earth

Solar wind has charged particles which are emitted from Sun's corona area. It has clouds called coronal mass ejections : make their way to Earth in 3-4 days.
They collide with the magnetic field of Earth . The particles leak into Earth's atmosphere , particularly near the south and north poles.
At that time, on polar atmosphere we can see these particles . These will be in the form of patterns produced by fire crackers.
