This happens at the spring and autumn equinoxes. Equinoxes occur twice a year, when the tilt of the Earth's axis is oriented neither from or to the Sun, causing the Sun to be located over the equator. They occur on the 20th or 21st of March (spring) and 22nd or 23rd September (autumn).

Why are the seasons in the order they are?
Seasons follow the same order in the Northern and Southern hemispheres but they are exactly reversed.Spring, Summer, Autumn, Winter and then the seasons cycle through again.Spring begins in September in the Southern hemisphere but in March in the Northern hemisphere. The "official" day that each season begins changes slightly from country to country, this is a local decision and varies by a few weeks eg the season starts on the 1st of the appropriate month or the 22nd of the month.Countries on or near the Equator do not experience a noticeable change of season or length of day compared to night.
If the earth stopped revolving when the northern hemisphere was pointed towards the sun would you have longer nights or days?
All you would have is a day where the Northern Hemisphere was pointed at the sun. The side opposite would be in permanent night. it would have nothing to do with Hemispheres but with which side is pointed to the sun. Alternate: If by 'pointed towards' you mean at the same angle as the current tilt, then the answer would be a little different. But the answer would depend on where you are. Or are you one of the many who assume that the northern hemisphere is the only one? If you are in the northern hemisphere, you would have longer daytime periods than night. It would be opposite in the southern hemisphere.
March 21st is an equinox What part of Earth is directly beneath the Sun on that day?
Don't understand your question. Equinox means "equal night", meaning the Northern Hemisphere and Southern Hemisphere both receive equal amounts of day and night. It signifies the beginning of Spring in the northern hemisphere and the beginning of Fall in the southern hemisphere.

What event signals the beginning summer?
It should be remembered that the seasons are diametrically opposed in the hemispheres. When it is summer in the northern hemisphere it is winter in the southern one. Seasons officially start and end on the solstices and equinoxes. The solstices are the days on which daylight or night time are the longest. When the day is longest in the northern hemisphere night is longest in the southern. The equinoxes are when day time and night time are equal which varies depending on your latitude. (Except at the equator)
What hemisphere was the moon in last night?
Since the Earth rotates all the way around every 24 hours, the moon is over both the eastern and western hemispheres for roughly 1/2 of every day. It's also over both the northern and southern hemispheres for roughly 1/2 of every four weeks.

Why are the night longer in winter?
Winter occurs at different times of the year for the northern and southern hemispheres, and both the seasons and duration of night are caused by the same thing! The earth rotates at a tilt in relation to how the sun faces the earth. During the winter, the sun is farther away from that part of the earth, and as such it spends more of its time facing away from the earth.

What are spring and autumnal equinoxes?
An autumnal equinox is when the day is just as long as the night and the days are getting shorter. This happens in late September for northern hemisphere and in late March for southern hemisphere. It is different in the two hemispheres because of the Earth's revolution around the sun.
