Because the Earth is tilted on its axis. In the winter, the Northern Hemisphere is tilted away from the sun, so the path you travel on the Earth is more in the dark. Note that this is not true all over the Earth. On the equator, the days and nights are always equal. In the Southern hemisphere, it's the opposite of the Northern hemisphere.
Don't understand your question. Equinox means "equal night", meaning the Northern Hemisphere and Southern Hemisphere both receive equal amounts of day and night. It signifies the beginning of Spring in the northern hemisphere and the beginning of Fall in the southern hemisphere.
March 20th or 21st
In the northern hemisphere, the autumnal equinox marks the first day of fall. An equinox happens twice a year, when the sun shines directly on the equator and the length of day and night is nearly equal.
latitude of the observer
June 21st is the summer solstice in the Northern hemisphere, and for the northern hemisphere it is the longest day of the year. In the Southern hemisphere June 21st is the winter solstice. This means it is the shortest day of the year. This happens due to the earth's 23 degree tilt. The equator, however, is right between the hemispheres. So the days and nights are of equal length.
Ther sun spends more time in the northern hemisphere, thus longer days and shorter nights. This is reversed when the sun spends more time in the southern hemisphere. At the equinox days, the sun spends time at the equator and the days and nights are equal.

They are equal.

The equator
Northern and southern hemisphere. And eastern and western hemisphere.
no
The seasons are already figured out . . . the seasons change on the equinoxes (days and nights of equal length) and on the soltices (days and nights are the most different in length)
A hemisphere is exactly 1/2 of the earth. We speak of the Western Hemisphere, the Eastern Hemisphere. the Southern Hemisphere, and the Northern Hemisphere.
At the Equator at the two Equinoxes, Spring and Fall.
Neither. All days are equal length.
