Detailed explanation-1: -In the ionosphere, the ions of the solar wind collide with atoms of oxygen and nitrogen from the Earth’s atmosphere. The energy released during these collisions causes a colorful glowing halo around the poles-an aurora. Most auroras happen about 97-1, 000 kilometers (60-620 miles) above the Earth’s surface.
Detailed explanation-2: -The aurora is formed from interactions between the solar wind streaming out from the sun and Earth’s protective magnetic field, or magnetosphere. The aurora is one manifestation of geomagnetic activity or geomagnetic storms.
Detailed explanation-3: -Auroras occur when electrons and protons from the Sun strike gas molecules in Earth’s upper atmosphere. As the solar particles encounter Earth’s magnetosphere, they are drawn along the magnetic field lines and funneled toward the North and South poles.
