What is the difference between a solstice and an equinox?
In simplest terms, an equinox represents a day with equal duration of day and night (Mar 21 and September 23) and thus we have a spring and a fall equinox.

Seasons are caused because of the Earth's changing relationship to the Sun. The Earth travels around the Sun, called an orbit, once a year or every 365 days. As the Earth orbits the Sun, the amount of sunlight each location on the planet gets every day changes slightly. This change causes the seasons.Why does equinox happen?
The dates of zero tilt of the Earth's equator correspond to the Spring Equinox and Autumn Equinox. Equinoxes occur when the axis of rotation of the earth (i.e. the line form the N to S poles) is exactly parallel to the direction of motion of the earth around the sun.What is the difference between autumnal and vernal equinox?
Day and night have approximately the same length. Autumnal equinox is near 22 September. The Spring Equinox is the first day of spring season and occurs when the sun passes the equator moving from the southern to the northern hemisphere.
