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.
No, the solstices and equinoxes mark the beginnings of the four seasons.
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,
The two seasons that begin with solstices rather than equinoxes are summer and winter.
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.
The two equinoxes.
equinoxes
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.
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.

A lot of things. equinoxes, solstices, (as a few) you need to elaborate more :)
Yes, the date of each of the equinoxes and each of the solstices varies from year to year due to the differences between a calendar year (365 or 366 days) and an average actual year (about 365.24219878 days). The dates of the solstices and equinoxes also vary depending on where you are on earth, since there are always at least two days in progress on earth at any given time.
The beginning of different seasons is marked by equinoxes and solstices. In the Northern Hemisphere, spring begins at the vernal equinox in March, summer starts at the summer solstice in June, autumn begins at the autumnal equinox in September, and winter starts at the winter solstice in December. Conversely, the Southern Hemisphere experiences the opposite seasonal timing. Thus, equinoxes and solstices serve as key indicators for the changing seasons.
