why are there places that dont have night time, and what places have constant daylight?

Question

we are thinking iceland but not sure why???? 2 adults and 1 teen debating.....

Answer 1

Only the polar circles.

Answer 2

Everything north of the arctic and south of the antarctic circles, from a certain date depending on latitude either have all daylight, or all darkness for a certain number of days, for some places, it's only a few hours, for other places, such as Barrow, Alaska, for example, it's several week (November to January).

The same places that have all darkness also have all daylight times, depending on their season, during summer, there is all daylight because the earth is pointing towards the sun in their hemisphere, so the sun never inclides away, or does it very little (so the sun will dwindle at the horizon for a bit then move up to the middle of the sky, and back down to the horizon but will never go down), in the winter, they are inclined away from the sun so it will always remain just below the horizone, and in some places, they are so far north or south that they don't even get twillight.

Right now, we just passed the equinox, so those same places get exactly 12 hours of daylight and darkness since the sun is at the equator, on November 22nd, Barrow Alaska will not see the sun again until January 18. Some places below the arctic circle but very close to it anyway experience a day where the sun only comes out for an hour or so, or goes down for an hour or so. In Mid July, Anchorage Alaska will have only 4 hours of darkness a day...

it's all caused by the inclination of the earth during it's rotation around the sun.

Answer 3

When the Northern Hemisphere (i.e. above the equator) is having summer (from June 21 to September 21), the north pole is tilting towards the sun. If you are ABOVE the Arctic Circle, even in the middle of the night (like at 2 a.m.) the sun is still visible, because at such a high latitude it doesn't set below the horizon.

BUT . . . in winter it is just the opposite. In a few months, the sun will not rise if you're above the Arctic Circle. The north pole is tilting AWAY from the sun, its rays don't strike the ground.

There is no place that is CONSTANTLY in daylight year-round. Only at both poles and only during their summer months.

Answer 4

north of the arctic polar circle in the northern hemisphere summer, you will have no nights.

Iceland won't work for that because it lies south of the arctic polar circle, but northern Norway, or northern Finland, or northern Sweden, will be fine.

Northern Canada will work also.

Clearly in the winter these regions never see the sun. In some cities there, they have special artificial lights and people go there for a couple hours each day, to remain sane and in good health.

Or else you can do the same thing in the southern hemisphere. But this would require a boat as none of the lands extend that far south, before you hit Antarctica itself.

Hope this helps

Answer 5

O.k. The orbit of the Earth has a slight wobble. Throughout the year the angle of the poles to the sun changes slightly. This causes the seasons. You may have noticed that in the Wintwer the Sun stays close to the horizon and in the Summer it is much higher in the sky. In the far north and south of the planet the sun gets so low in the winter that it doesn't get above the horizon at all and in the winter it is so high in the sky that it stays above the horizon for 24 hours for months.

Answer 6

Two ADULTS are debating this????

Actually, nowhere on Earth has "constant daylight." Oh sure, the arctic regions get sunlight for a few months at a time...but they get equal periods of darkness the rest of the year.

Answer 7

Only the very northern tip of Iceland has perpetual daylight, and then only in the summer, as it is north of the Arctic Circle. Other posts explain the bigger reasons.

Answer 8

The polar circle, where the sun does not rise more than 10º
and circles the horizon in summer time. In winter it is dark
all night and the constant daylight is in the South Pole, or
Antarctic Pole.

Answer 9

In the middle of summer it never gets dark inside the arctic circle and in winter never gets light.
Imagine the sunlight is behind the earth at night,in the summer some light leaks over the top of the north pole so even at night it is light.In the winter the earth tilts away from the sun so the opposite occurs.

Answer 10

the reason for the constant daylight or night time for months on end is dew to the way the earth spins and rotates round the sun you fint the closer to the pole's you go this happens more the two pole's have months of daylight and then months of darkness hope this helps

Answer 11

Check out Tronso in the arctic circle. It's to do with the tilt of the earth at different times of the year. Tronso has a few months of darkness with absolutely no sun.
