Here are few questions

  • Define Aurora Borealis .
  • Which field is responsible for visibility of aurora Borealis.?
  • Can it be predicted where we can see aurora Borealis.
  • When does aurora Borealis occur?

Aurora Borealis is also well known as northen lights.

This happens because earth's magnetic field reacts with suns charged energy particles.

Mostly found in high altitude mountain regions

Two questions which arises in my mind about aurora borealis are:

  1. Why does aurora borealis occur?
  2. Why does aurora borealis occur in a particular time of the year?

Answers:

  1. As solar wind approaches the Earth, it meets the Earth's magnetic field. 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 aurora borealis.
  2. Aurora borealis is active the whole year. Since it needs to be dark in order to see aurora borealis in the sky, late August/September through the very beginning of April is the best time to go to a destination located in the aurora zone for a chance to see them.

Note: These are the questions which arises in my mind only. It may differ from person to person.

Hope you could understand.

If you have any query, feel free to ask.
