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.

mountains form from collision of earths plates
Answer:
2.656 km
Explanation:
Velocity of sound in the air = 332 m/s
time t= 8 sec

Florida has lightening quite often because
Florida receives a lot of heat through out the year, air close the ground is warmed and frequent sea breezes (Florida is surrounded by seas and oceans) provide the necessary lift and moisture for the formation of thunderstorms. This why lightning is common Florida
Because the toxins from gas are not good to breath in and eventually we will al die from it
