There are two equinoxes evry year, in September and March, and a year passes between one vernal equinox and the next (in either hemisphere).
Pretty much, yes. You have the spring (vernal) and autumn (autumnal) equinoxes, so it's around that time. Midsummer's day is around the first day of summer. But the equinoxes aren't precisely (to the smallest fraction of a second) halfway between, because the velocity of earth's orbit is constantly changing throughout the year.
Spring Tides. That is the High tide is very high and the low tide is very low. When the Sun, Earth and Moon are at 'right-angles to each other, then we have Neap Tides. The height range between high and low tides is much less than Spring Tides.
The Earth's shadow is larger than the Moon's shadow because the Earth is much larger in size and has a greater surface area for casting shadows. The Moon's shadow is smaller in comparison, especially during a solar eclipse when the Moon passes between the Earth and the Sun.
The average time between two successive sunspot minima is around 11 years, known as a solar cycle. This period is characterized by a decrease and increase in sunspot activity. However, the length of each solar cycle can vary, ranging from around 9 to 14 years.
It really depends if it is Spring, Summer, Fall, or Winter. When it is winter, the nights are much longer. When it is summer, the nights are much shorter. When it is Spring or Fall, the night time'will be as long as the day simply because of the Equinox.
You gain daylight after the spring equinox how much depends on your latitude .
A tropical year, which is a year based on season and is about 20 minute shorter than a sidereal year (based on localization of star).
Yes, pretty much so. On the Equinox (which happens to be today, March 20, 2014) there is exactly 12 hours between sunrise and sunset. Bear in mind that it's light enough to see for a few minutes before sunrise and a few minutes after sunset, so it SEEMS like the day is a bit longer than the night - but they are equal. That's what "equinox" means; "equal nights".

On the first day of spring you get 12 hours of each (it's the equinox). After that you get more daylight every day until the last day of spring ... how much more depends on how far from the equator you live.
