what determines the portion of the moon that you see at night
Depends on where you are (latitude) and the time of year.
at the time answering this its was 13:13 hrs - daylight PM
Night does not have a specific start time. It refers more to a lack of sunlight rather than a time. Though in the high and low latitudes it may even be broad daylight even at 'night'.
They can see in dayligh, it is just that they fly at night because the suns not out, so it doesnt pucture there wings, and there is less predators and competition. HOWEVER some flying foxes fly in plain daylight.
what determines the portion of the moon that you see at night
Daylight and night are caused when the Earth spins, making different parts face toward the sun and away from it.
daylight
6 hours
Your distance from the equator determines how many hours of sunlight you have on the solstices.
actually, more at night
A solar eclipse can happen only in places that are in daylight. While those places are in daylight, there are, of course, other parts of the earth where it is night. So a solar eclipse can happen when some parts of the earth are at night, but it can happen only where it is daylight.
...at night
The sunrise.
The only places which have 6 months daylight and 6 months night are the North and South poles.
It depends on where you are in the world; the more North you are, the less daylight time there will be. At the North pole, there is no daylight at all, and at the South pole, there is no night at all. And at the equator it always stays 50% daytime and 50% night time.
No. Arizona does not use daylight savings time.
