Does the autumnal equinox mark the beginning of fall for both hemispheres?
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.
What is the difference in position of earth and the sun at the summer solstice compared to there position during a winter solstice?
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
Are the days longer or shorter in the northern hemisphere right after the autumnal equinox?
The word 'Equinox' means equal day and night. The Autumnal equinox falls on the 23rd September. So any date after this, say 26th September, in the Northern Hemisphere the nights are longer than the days. Conversely, in the Southern Hemisphere the days are longer than the nights. At the Vernal (Spring) Equinox, 21st March, the whole system is reversed. There are four days in the year when there is a change. For the Northern Hemisphere; Vernal Equinox ; day and night are the same length. After this date the days are increasing and night is decreasing. until; Summer Solstice; Daylight is at a maximum and night is a minimum. Autumnal Equinox ; day and night are the same length. After this date that nights are longer than the days. Winter Solstice ; Daylight is at a minimum and night is a maximum. However, in the Southern Hemisphere , the whole system is reversed !!!! Vernal Equinox ; day and night are the same length. After this date the days are decreasing and night is imcreasing. until; Summer Solstice; Daylight is at a minimum and night is a maximum. Autumnal Equinox ; day and night are the same length. After this date that days are longer than the nights. Winter Solstice ; Daylight is at a maximum and night is a minimum. So in the USA or Great Britain(Northern Hemisphere), when its Summer, it is Winter in Australia & South Africa (Southern Hemisphere). Similarly at the poles. North Pole ; Summer ; 24 hours daylight and South Pole 24 hours darkness. North Pole ; Winter 24 hours darkness and South Pole 24 hours daylight. S
When are day and night the same length and what is the phenomenon called?
The length of day and night is equal at the Vernal and Autumnal equinox.
Day and night are equal at?
Equal periods of sun-up and sun-down are all near March 21 and September 21, everywhere on earth, including the equator. Those days are often called the "equinoxes", but the equinoxes are actually the points in the sky where the sun appears to be located on those days.

Yes - at the summer and winter equinox
Where is the sun when there is a equinox and how is the day and night time compare at that time?
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.
How many times per year do you have days in which the number of hours day and night equal what are the names of those days?
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.

About how many hours of daylight will there be in the Northern Hemisphere on the fall equinox?
The equinox is the point in time where the Sun crosses the equator and there is no tilt to the Earth, thus there are approximately the same number of hours of light and darkness in both hemispheres. The term "equinox" comes from the Latin aequus (equal) and nox (night).
