How does day and night work in the north and south poles?

The Earth is tilted at an angle of about twenty three and a half degrees.  This is the reason why North and Magnetic poles are not at the same place.  \n\nAnyway, in the Northern winter, the North Pole is angled away from the Sun, with the South Pole therefore being angled towards the Sun.  The result is 24 hours night in the north, 24 hours day light in the south.  This is the southern summer.\nNow remember that the Earth maintains this angle throughout its orbit.\nSix months later, the Earth is on the other side of its orbit around the Sun.  Still maintaining the same tilt, now the North Pole is receiving 24 hour day light, and the South Pole is in darkness.  Northern summer, southern winter.\n\nThe Arctic and Antarctic circles mark the limit of this 24 hour daylight, and the Tropic of Cancer (North) and the Tropic of Capricorn (South) mark the limits of the maximum travel of the Sun at it appears in the northern and southern skies.\n\nAt the Spring and Autumn exquinox, the Earth is such that the Poles are receiving equal amounts of sunlight.  Equinox means "equal night".  \n\nI down know any particular websites but try the NOAA and BBC weather sites.\n\nADDITION: To Glenn Blaylock.  Thank you very much for the correction.  I'll read up on my error.

Norway has 6 months of Daytime and 6 months of Night\nCertain portions of Antarctica and Arctic circle also have 8 months night and 4 months daytime\nFalkland Islands and Newfoundland have 4 months of Daytime and 8 months night

It's all to do with the angle of the earth.  It doesn't sit in an upright position, rather it reclines at and angle of 23 degrees.  It also rotates around the sun once a year which means that at times parts of the earth are pointing towards the sun and other parts are pointing away.\n\nThe further north or south you go the more pronounced the difference in daylight hours is.  For example, if you venture into the Arctic Circle (within 23 degrees of the pole) you can have 24 hour daylight during the summer months and 24 hours darkness during the winter months.\n\nBecause India is closer to the equator the difference in sunrise and sunset times is less variable than it is in Australia or the UK.  In the UK for example at this time of year it's daylight up until about 10PM but during the winter months it's dark by 4PM.

In North pole of Earth there is South pole of Earth's magnet and in the South pole of Earth there is North pole of Earth's magnet.

one face is south and the other face is the north pole

Because the earth is tilted on its axis, we have seasons.  The seasons vary the length of daylight depending on the season.  When it is summer, and the days are long, in the northern hemisphere, it is winter in the southern hemisphere and the days are short.\n\nIf you think about this, you will realize that it can't be true of the equator.  Where the two hemispheres meet, the days don't vary by season.  The farther you are from the equator, the greater the length of the day (or night) -- so at the poles the sun deosn't set in mid-summer or rise in mid-winter.

Stars near the north pole seem as if they are moving in a circle around the point in the sky that would be directly up.  You can find pics of this on a lot of astronomy websites.  Here is en elapsed time photo of the north pole at night:  http://astro.wsu.edu/worthey/astro/html/im-sky/north-pole-star-trails.jpg

An excellent question!\n\nSince there are no boundries in the polar regions — the Arctic is ocean and the continent of Antarctica has no nations - time zone lines follow longitude lines in these places. \n\nSince all longitude lines come together at the poles, you can walk through all of the time zones in seconds by walking around the pole that marks the South Pole. Imagine walking around the pole in the photo above on this page. \n\nThere's no North Pole pole since drifting sea ice covers the location and anything put there, such as an automated weather station, drifts away. Our story about the Christmas Day North Pole temperature has more on this. \n\nAs a practical matter, having all of the time zones means there is really no time zone for the polar regions. In Antarctica, the U.S. stations uses New Zealand time because most Americans who go to Antarctica for the U.S. Antarctic Program fly to and from there via Christchurch. \n\nOnce you arrive in New Zealand for the U.S. Antarctic Program, you could fly to Antarctica, everywhere that a U.S. airplane could take you on the continent, and back to Christchurch without ever having to change the time on your watch. \n\nSince the only station at the South Pole is the U.S. station, the time used there is New Zealand time.\n\nOther nations tend to use their home time zones in Antarctica, which makes radio and e-mail contacts simpler. \n\nThe permanent research stations in the Arctic are in countries, such as the Barrow Science Center in Barrow, Alaska, and these use the local time. When researchers venture out onto the Arctic Ocean ice, they can use any time the wish. But, in most cases it's probably easier to use the time for the institution, such as a university, that you are working for. \n\nYou can learn a lot more about what goes on in the polar regions by going to our Science, life and travel in the polar regions page

Depends on the time of year.\nSummer solstice = 0\nWinter solstice = 24\nSpring/fall equinox = 12\n\nAll other days, some gradual change from 0 to 24. This is true of any land within the Arctic or Antarctic circles (of course the times are reversed for the Arctic circle). Those circles are defined by the places on Earth that have at least one day of complete light and complete darkness during the year.

u might have heard abt latitudes. Sun light constantly falls on earth. as earth moves different past of earth receives light and this is what we term as day and night. Latitudes help in determining times and it takes 15mins for sun to pass from one latitide to another. In other words we have time zones ever heard of green whtch time zone. This way, time is calculated with respect to sunrise and sunset. \n\nThus its all depending on how sunlight reaches in ur region..!

This theory sounds like a bunch of balogna (pronounced baloney). The reason that there is day and night is that a giant dragon eats the sun at night. And in the morning, it lays a new sun.\nBut seriously, day and night occur because the earth spins on its east-west axis. On some other planet (Neptune, I think) the sun rises and sets on its north-south axis.

The poles are not good places for observatories, from a purely geometric point of view. From the north pole, you can see only half the sky, the same half night after night for six months. Then during the summer the sun is in the sky all the time and you can't see anything except the sun.\n\nA similar problem exists at the south pole, except that the seasons are reversed.\n\nFrom the equator you can see the entire sky over the course of a year. On any single night, you can see only some of the sky, but if you wait a year you can see it all.

The further north you are, the better results you will have.  Typically, you need to live above 53 degrees latitude to see them on a regular basis, but with BIG solar storms, the aurora can be seen as far south as 30 degrees.\n\nWinter months tend to be better viewing months because the aurora occurs in the shadow of the earth from the sun.  The North Pole is mostly in darkness during this time of year.  Also, the air is clearer because it's cold and there's less moisture in the air.  At night, the best times are the hours near midnight.\n\nIn the continental U.S., you can see the aurora in the Northernmost states a handful of times throughout the year, based on solar activity.\n\nBelow is a site to check out to see what the present solar activity is like and the forecast.  This will help determine which nights might provide success.

The North pole is over sea, South is over land.\n\n\nPolar bears in the North, Penguins in the South.

Night and day occur at the same time on opposite sides of a planet.

The earth has two magnetic poles, a north pole and a south pole.\n\nThe effect of both poles can be detected by a good compass from anywhere on earth.

The pole in the north direction of earth is the south magnetic pole of earth's magnet.\n\nThe position of magnetic pole is changing but not the pole itself. If the pole cahnges then the magnetic needle in the compass will deflect in the opposite direction.
