Two questions which arises in my mind about aurora borealis are:
- Why does aurora borealis occur?
- Why does aurora borealis occur in a particular time of the year?
Answers:
- 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.
- 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.

Explanation:
Of the five oceans, the one with the greatest average depth is the Pacific, with about 4300 meters.
The reason is that this ocean is located on the great plate of the Pacific whose convergent margins are crossed by deep oceanic trenches under which this plate subducts.
In fact, the greatest ocean depth is also found in this ocean and corresponds to the Challenger Abyss, in the Mariana Trench, which reaches a depth of 11 km.
