Answer 1

1. The exosphere is characterized by aurora Australis and aurora borealis.
2. An aurora is referred to as polar light. Northern lights (Aurora Borealis) or Southern lights (Aurora Australis) is a natural light display in the Earth’s sky, predominantly seen in the high altitude regions (around the Arctic and Antarctic).
3. Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind due to magnetic storms, which are seen as unique/multicolored fireworks hanging in the polar sky during midnight.
4. Most auroras occur in a band known as the auroral zone.
