why do polar regions experience continuous daylight for 6 months and continuous nighttime for the next 6 month

Answer 1

The Earth is tilted at an angle, and spins around that angle.

As it orbits the sun, the northern hemisphere receives more sunlight during half the orbit, and the southern hemisphere receives less. The poles are at the most extreme regions, and thus have the most extreme periods of sun exposure.

This is the same reason that we have seasons. The orbit of the Earth is circular enough that distance from the sun has little effect. One will note that the southern hemisphere has opposite seasons than the northern, because of the tilt.

Answer 2

As John and Scrappy have both said - the earth is tilted at an angle, it's about 23.5 degrees (varies slightly). The poles are at approximately the one and seven o'clock positions.


If you imagine a light bulb in the middle of a room which represents the sun and you have a globe in your hands - tilt the globe slightly so that the north pole is facing away from the lightbulb and is in shadow, that's roughly how the world is at the moment. Now, keeping the globe still, if you walk half way around the room the north pole will now be facing towards the lightbulb - this is how the planet is in summer.

The further towards the poles you go the longer or shorter the days and nights are. At the equator it's constant throughout the year.

It's not strictly six months of day and six months of night. It would depend very much where you were but even at the poles you'll find about 3 months of night followed by 3 months in which the days get progressively longer followed by 3 months of unbroken day and finally 3 months when the days get shorter.

Answer 3

No, but for a few days in the summer it is daylight continuously way up north but the sun is close to the horizon. The days stay very long but gradually shorten into the fall when they reverse and the nights become really long and finally in winter you have a few days with no daylight.

Answer 4

Because the earth is tilted. let me explan. let say you had a bouncy ball with a touth pick in it. now that touth pick is the north and soulth pole. now pretend that bouncy ball is divided into forths. the middle is the is the cut is the equarter and the top and bottom is the are the tropics. now when the earth is tilted like this ( / ) it spins like this for six mounths and give day in nourth and night in soulth, and when it tilted like so ( \ ) its night in nourth and day in soulth. thats alsow why its summer in USA and Winter in lower soulth america. hope i answered your Q and then some.

Answer 5

has to do with day trippers and night slippers.
