Definition of equinox 1 : either of the two points on the celestial sphere where the celestial equator intersects the ecliptic. 2 : either of the two times each year (as about March 21 and September 23) when the sun crosses the equator and day and night are everywhere on earth of approximately equal length.
What is equinox and solstice in geography?
An Equinox is a day when daylight and night-time become equal. A Solstice is a day either having the longest or the shortest day of the year. 2. There are two types of equinoxes i.e spring and autumn equinox. There are two types of solstice i.e summer and winter solstice.
What is an equinox in astronomy?
The term equinox, like solstice, finds its origin in Latin with the roots aequus meaning Equal and nox meaning Night. Astronomers define the equinox as the moment the Earth’s Equator on its axis passes the same plane of the Sun’s equator, but its name reveals more of what we experience of these March and September
What happens during the time of equinox?
An equinox is traditionally defined as the time when the plane of Earth’s equator passes through the geometric center of the Sun’s disk. This occurs twice each year, around 20 March and 23 September. In other words, it is the moment at which the center of the visible Sun is directly above the equator.
What is special about equinox?
During an equinox the earth’s north and south poles are not tilted towards or away from the sun and the duration of daylight is theoretically the same at all points on the earth’s surface. Hence the name, equinox, which is derived from the Latin meaning equal night.

On these days, the nights are equal in length at latitudes Lxb0 North and Lxb0 South. The word equinox comes from two Latin words meaning equal and night.

The equinoxes are the only time when both the Northern and Southern Hemispheres experience roughly equal amounts of daytime and nighttime.
What is difference between equinox and solstice?
Equinox vs Solstice While the solstices result in a change of the length of night and day, the equinoxes do not. The summer and winter solstices result in the longest and shortest day of the year respectively while the equinoxes result in an equal amount of daylight and darkness received all across the earth.

What happens during an equinox?
At the equinox, the sun crosses the celestial equator to enter the sky’s Northern Hemisphere. We have an equinox twice a year spring and fall when the tilt of the Earth’s axis and Earth’s orbit around the sun combine in such a way that the axis is inclined neither away from nor toward the sun.
What is an example of a equinox?
Either of the two times during a year when the sun crosses the celestial equator and when the length of day and night are approximately equal; the vernal equinox or the autumnal equinox.

What are three facts about an equinox?
