yes, 12 hrs day 12 hrs night
The length of day and night is equal at the Vernal and Autumnal equinox.
That is depending on what you regard as the autumnal equinox. The autumnal equinox in the northern hemisphere is in September and it marks the start of autumn. In the southern hemisphere the autumnal equinox is in March and it marks the start of autumn. So looking at in that way, you can say yes. Of course those are two different dates on the calendar, so the autumnal equinox in one is happening at the same time as the spring equinox in the other. It is the same equinox, but where on Earth you are, determines which equinox it is. As autumn starts in one hemisphere, spring is starting in the other. So on that basis they don't mark the start of autumn in both hemispheres. It is never the same season in both hemispheres.
The maximum elevation of the Sun occurs at the summer solstice, and the minimum at the winter solstice. During an equinox, the Sun is directly above Earth's equator. Sorry, but if you are Savannah Schoenherr, DO NOT COPY
No, an equinox is when day and night are approximately the same length. It does not specifically affect the brightness of the sky.
In the northern hemisphere, the days become shorter right after the autumnal equinox. This is because the amount of daylight decreases as the hemisphere tilts away from the sun, leading to shorter days and longer nights.
During the Autumn equinox the length of the day and night are nearly equal. The length of the day on the equinox is approximately twelve hours.
Equinox is the name given when the day is made up of the same amount of day and night. There are two Equinoxes a year the Autumn Equinox and the Spring Equinox.
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).

In the Spring and Fall equinox, night and day have the same number of hours. Equi = equal.
Yes.

Yes - at the summer and winter equinox
The sun is at the celestial equator, appearing to go Northwards at the vernal equinox and southwards at the autumnal equinox. The word equinox derives from the Latin roots for "equal" and "night" and so, not surprisingly, the night time is the same as day time: 12 hours each.
When night and day are approximately of equal length occurs twice per year. In the northern hemisphere these days are called the Vernal Equinox (20-21 March) and the Autumnal Equinox (22-23 September). However, as these seasons are reversed in the southern hemisphere, current usage is the March Equinox and the September Equinox.
