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.

Earthquakes occur along plat boundaries and faults. Most earthquakes happen along the edge of continental and oceanic plates. Faults are found in the middle of the plates. They're like cracks that form when the different parts of the plates don't move in the same direction.
The haka is a traditional war cry, war dance, or challenge in Māori culture. It is a posture dance performed by a group, with vigorous movements and stamping of the feet with rhythmically shouted accompaniment.[a]
War haka were originally performed by warriors before a battle, proclaiming their strength and prowess in order to intimidate the opposition, but haka are also performed to welcome distinguished guests, or to acknowledge great achievements, occasions or funerals, and kapa haka (performing arts) groups are very common in schools.
