Its the orientation of the earths rotational axis that defines the equinox, the axis remains parallel throughout the orbit of the sun, and when its side on to the sun (spring and autumn), thats the equinox (equal length of day and night).

What occurs when the sun's most direct rays hit the equator and the day experiences equal amounts of light and dark?

The Sun is never ON the equator, it is above the equator twice a year - the spring equinox and the fall equinox.


An equinox occurs on the same day at the same time in both hemispheres?

Correct. The March equinox, which is typically March 21 but can vary by a day either way, is the spring equinox in the northern hemisphere, because the Sun us rising into the northern hemisphere. At that very same moment, it is the autumnal equinox in the southern hemisphere, because as the Sun is moving INTO the northern hemisphere, it is moving away from the southern hemisphere. The September 21 equinox sees the Sun moving south of the equator, so the spring equinox in the south, while it is the autumnal equinox in the North.


What is the length of daytime in autumnal equinox?

Approximately 12 hours of Sun-over-the-horizon. (Same as the vernal equinox)


How do you explain the equinox?

An equinox happens twice a year, when the tilt of the Earth's axis is inclined neither towards or away from the Sun, the centre of the Sun being in the same plane as the Earth's equator. The term "equinox" is derived from the Latin "aequus" (equal) and "nox" (night). Because around the equinox, day and night have an approximately-equal length.

On what line of latitude is the sun directly over at the Spring and Autumn Equinox?

the sun is at 0 degrees during an equinox. It is aligned with the equator.


What day is it when the sun is overhead south of the equator?

The sun is directly over the southern hemisphere from the September equinox until the March equinox.


What is enquinox?

An equinox is the moment when the Sun is directly over the Earth's equator, and the apparent position of the Sun at that moment. Daylight savings follows the equinox.


Twice a year the sun is directly over the equator this is called the?

The Sun is directly overhead the equator two times per year, known as the Equinoxes. In the northern hemisphere, the Spring Equinox occurs on March 20 and the Fall Equinox occurs on September 22.


How many degrees latitude will the sun be at noon during Fall Equinox 2008?

At the equinox, the Sun will be directly above the equator, 0 degrees latitude.


What is it called when the sun is directly above the equator?

This happens twice a year at on of the "equinox" (the spring equinox or the fall equinox) At noon if you are on the equator at thet oment the Sun is at the "Zenith".


What side of the earth is closest to the sun during an equinox?

The side of the earth that is closest to the sun is always the sunlit side; this remains true at the equinoxes. An equinox happens at a single moment, and the part of the earth receiving sunlight at these moments will be different from equinox to equinox, because the equinoxes are not in synch with whole days.


What occurs when the sun's most direct rays hit the equator and the day experiences equal amounts of light and dark?

The Sun is never ON the equator, it is above the equator twice a year - the spring equinox and the fall equinox.


Where is the sun when there is a equinox and how is the day and night time compare at that time?

The sun is at the celestial equator, appearing to go Northwards at the vernal equinox and southwards at the autumnal equinox. The word equinox derives from the Latin roots for "equal" and "night" and so, not surprisingly, the night time is the same as day time: 12 hours each.


During the autumnal equinox what does the sun do?

The Sun doesn't do anything at such. The Autumnal equinox is more down to the position of the Earth on its orbit of the Sun. The sun is directly over the equator and the amount of daylight and darkness is about equal around the world.


What is it when the sun is directly over earth's equator?

The equinox.
