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.

Which two seasons begin with solstices rather than equinoxes?
The two seasons that begin with solstices rather than equinoxes are summer and winter.
Why the dates of the solstices and equinoxes vary?
The dates of the solstices and equinoxes vary because Earth's orbit around the sun is not a perfect circle, but an ellipse, causing the speed at which Earth moves around the sun to vary. Additionally, gravitational pull from other celestial bodies, such as the moon and planets, can also influence Earth's orbit and the exact timing of these astronomical events.
When are the solstices and equinoxes each year?
The Solstices' are the longest day [June 21 or 22(in northern hemisphere)] and Shortest day in [December 21 or 22(northern hemisphere)]. The Equinoxes happen every 6 months in September 21st and March 21st, they're also another word for Daylight Savings Time.
If earth's axis were tilted 45 degrees at what latitudes would the sun be directly overhead on the solstices and the equinoxes?
If Earth's axis were tilted 45 degrees, the sun would be directly overhead at latitudes of 45 degrees north on the summer solstice, 45 degrees south on the winter solstice, and would pass through the equator on both equinoxes.
What are the two equinoxes?
The two equinoxes occur every spring and autumn. The "equinoxes" are two points on the map of the stars. The center of the sun reaches and passes one of them at some moment around March 21, and the other one at some moment around September 22. At those moments, the sun is directly overhead some point on the earth's equator, and every place on earth has roughly equal periods of sun-up and sun-down on that day ... the only two times in the year when these things happen.
The equinoxes and solstices mark the midpoints of the three seasons?
No, the solstices and equinoxes mark the beginnings of the four seasons.
What are the difference between the equinoxes and the solstices?
The equinoxes and solstices are the first days of seasons. On the equinoxes, night and day is the same length. On the solstices, the day is either the longest or the shortest day of the year, depending on which solstice it is and which hemisphere you are in,
Which two seasons begin with solstices rather than equinoxes?
The two seasons that begin with solstices rather than equinoxes are summer and winter.
What occurs between the two solstices?
The two equinoxes.
What occurs midway between the dates of the summer and winter solstices?
equinoxes
Does the leap day affect when equinoxes and solstices occur?
Yes. If we did not insert the leap day during leap year, the calendar date of the equinoxes and solstices would change and eventually come at very different times in the calendar year. The whole purpose of Leap Year/Leap Day is to keep our calendar aligned with the equinoxes, solstices, and seasons in general.
How long does a season last?
91 and a fraction days. The dividing points are the two solstices and two equinoxes. You can see the precise dates of the equinoxes and solstices on the "Earth's Seasons" web site at the US Naval Observatory, at the link below.
How are the solstices and equinoxes related to the seasons?
" seasons are the manifestation of solsticesand equinoxesand are markers of the seasons
How does the revolution of the Earth correlate to the solstices and the equinoxes?
The revolution of the Earth around the sun causes the changing seasons and the positions of the solstices and equinoxes. The solstices occur when the Earth's axis is tilted most toward or away from the sun, leading to the longest and shortest days of the year. The equinoxes occur when the tilt is at a right angle to the sun, resulting in day and night being of nearly equal length.
How solstices and equinoxes different?
Equinoxes are the two points among the stars where the sun's apparent annual path crosses the celestial equator. Solstices are the two points among the stars where the sun's apparent annual path reaches its extremes, north and south of the celestial equator.
What is happening every half year?
A lot of things. equinoxes, solstices, (as a few) you need to elaborate more :)
What are solstices and equinoxes and how are they related to the seasons?
There are two solstices. they are the summer solstice (first day of summer), and the winter solstices (first day of winter An equinox is when day and night are the same length. like solstices, there are two of them. The Autumn equinox (first day of autumn), and then the spring equinox (first day of spring).
