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.
Hope you could understand.
If you have any query, feel free to ask.
In distance, it's something like maybe 245,000 miles ... corresponding to the
several Apollo missions during which a Command and Service module entered
lunar orbit and swung around the back side of the moon with astronauts aboard.
The farthest from Earth that a human has ever gone <em>and walked on solid ground</em>
is roughly 238,000 miles, corresponding to the six Apollo missions that landed
six pairs of astronauts on the near side of the surface of the moon, between 1969
and 1972 .
Answer:
New England's rum is traded for slaves in Africa. The slaves are brought to Cuba to grow sugar. Cuban sugar is exported to New England, where it is distilled into rum.
Explanation:
The transatlantic slave trade was also called the “triangular trade” for the triangles formed by the trade routes. One set of routes carried sugar and molasses from the Caribbean to the New England colonies, where it was turned into rum. The rum was sent to Africa and traded for slaves. The slaves went to the Caribbean, where they worked on sugar plantations.
