Main Body

Formation of Northern & Southern Lights: Sun emits high energy particles as solar flares. When they reach Earth, earths magnetic field interact with them. Some particles are captured in Earths magnetic field. This energy release leads to several light formations.

Impact of lights on: Interaction with upper atmosphere gas & possible breakdown (O3 ← O2+H2O). Potential widening of Ozone hole due to larger pressure of free radical. Disruption of satellite communications. Impact on electronic devices. Travel may be affected. Certain regions attract more tourists. There are several impacts both positive & negative.
