At the equinox day and night are of the same length all over the world because the Sun is in the plane of the Earth's equator, and that happens on March 21 and September 22 each year.

Which latitudes have the smallest annual change in daylight hours?
tropics
Which phenomenon occurs when the Sun crosses the plane of Earths equator?
The Equinoxes - Autumnal and Vernal (or Spring). The hours of daylight equal the hours of darkness.
Which latitudes would experience the fewest hours of daylight on December 22?
December 22 is close to the northern hemisphere's winter solstice (December 21), when the Sun is furthest south. At that date the Sun does not rise above the horizon at all latitudes north of the Arctic Circle (approximately 66.5 degrees north). They therefore have zero hours of daylight.
What do you call the two times a year when the earth has twelve hours of daylight and twelve hours of night because the poles are not pointed towards or away from the sun?
The Summer and Winter solstices.
For how many months of the year does the north pole receive no insulation?
The north pole recieves 12 hours of daylight only on the two equinoxes, not for the entire months of march and september.
When are the solstices and the equinoxes?
Equinoxes are when there are twelve hours of daylight and 12 hours of darkness. The autumnal equinox is on September 21st on average, and the vernal equinox is on March 21st on average. You can tell that the seasons have changed and the equinoxes and solstices have occured because the amount of sunlight changes and temperatures also change. Solstices are when there is either the shortest or longest amount of daylight. The summer solstice is when there is the longest amount of daylight. After the summer solstice, days begin to slowly get shorter until the autumnal equinox. The winter solstice is when there is the shortest amount of daylight. After the winter solstice the days get longer until you reach the vernal equinox.
What event signals the beginning summer?
It should be remembered that the seasons are diametrically opposed in the hemispheres. When it is summer in the northern hemisphere it is winter in the southern one. Seasons officially start and end on the solstices and equinoxes. The solstices are the days on which daylight or night time are the longest. When the day is longest in the northern hemisphere night is longest in the southern. The equinoxes are when day time and night time are equal which varies depending on your latitude. (Except at the equator)
The first days of summer and winter called solstices?
winter has the shortest amount of daylight and summer has the greatest amount of daylight./
Does the equinoxes occur during summer and winter?
There is no such things as summer and winter equinoxes. You have spring and autumn equinoxes, when the amount of daylight and darkness are equal. In summer and winter you have solstices, when you have the longest and shortest days in terms of the amount of daylight. The equinoxes are when the Equator transits the Ecliptic making the Sun appear as if it is moving either North or South depending on what part of the Ecliptic the Earth is in relative to it's rotation around the Sun. March and September. Called the Spring and Autumn equinoxes and when one hemisphere is in the Spring Equinox, the other is in the Autumn Equinox. Same point on the Ecliptic. "Beware the Ides of March."
What event signals the beginning of summer?
Some events that signal the beginning of summer are:Memorial Dayschool getting out for the summerpublic swimming pools openingweather getting hotter
Which latitudes have the smallest annual change in daylight hours?
tropics
Does the equator have anything to do with hours of daylight?
Your distance from the equator determines how many hours of sunlight you have on the solstices.
Is the autumnal equinox the longest day?
An equinox is not the shortest day. It has the same amount of daylight and darkness. The solstices have the longest and shortest days. The winter solstice is the shortest day of the year in terms of the amount of daylight.
What is the relationship between daylight and nighttime on an equinox?
Days become shorter from the Summer Solstice in June [the longest day of the year] through the Winter Solstice in December [the shortest day of the year] , when the days begin growing longer again. [At the Vernal and Autumnal Equinoxes, midway between the solstices, the days and nights are of equal lengths.]
How many times each year do you have days in which the day and night are of the equal duration?
The Equinox (Vernal & Autumnal) There are only two times of the year when the Earth's axis is tilted neither toward nor away from the sun, resulting in a "nearly" equal amount of daylight and darkness at all latitudes. These events are referred to as Equinoxes
Which phenomenon occurs when the Sun crosses the plane of Earths equator?
The Equinoxes - Autumnal and Vernal (or Spring). The hours of daylight equal the hours of darkness.
What are the days March 22 nd September 22 called?
These are the spring and autumn equinoxes, and are days when the daylight and darkness are equal.
