Why is the sun visible for so many hours of the day in Alaska?

Every place on Earth, when averaged out over a year, gets 6 months of daylight and 6 months of darkness. At the equator this daylight and darkness is spaced out in about 12 hour intervals (day and night). However, because of the tilt of the Earth's axis of spin, as one move towards the poles the length of night and day changes with the seasons until when you reach the poles, daylight lasts for 6 continual months and darkness lasts for 6 continual months. Alaska is near the North pole, so during summer the days are very long.


How many hours of darkness are there in one day?

It depends on where you are and what season it is. If you are at the equator then there is 12 hours of daylight and 12 hours of night. If you are above the arctic circle then during the winter there is 24 hours of darkness each day, this will occur on Dec. 21st. If you are further above the arctic circle the darkness can last for months. During the summer there will be 24 hours of daylight on June 21st, and again this can last for months if you are very far north. The same is true for the South pole as well.


How many hours of darkness are there in one day north of the Arctic Circle or south of the Antarctic Circle?

North of the Arctic Circle and south of the Antarctic one, the periods of daylight and darkness both vary from zero to six months, during the course of a year.


What would happen if earth axis were parallel to the sun?

I think you meant to ask: " What would happen if the Earth's axis were laying down flat in the plane of the Earth's orbit, so that one end of it pointed directly at the sun every six months ? " If that were the case, then Half of the Earth would have 24 hours of daylight once a year. On the same day, the other half would have 24 hours of darkness. Let's say you're at a place where it's 24 hours of daylight: The closer you are to one of the poles, the more days after that would continue to be daylight around the clock, for the next 3 months. Eventually, after that number of days, you'd begin to have nights, very short at first, but getting longer and longer for the rest of the 3 months. After 3 months, every place on Earth would have 12 hours of daylight and 12 hours of darkness. For the next 3 months, your hours of darkness would increase, while on the other half of the Earth, the hours of daylight would increase. After 6 months, your half of the Earth would have 24 hours of darkness, and the other half would have 24 hours of daylight. Now, the closer you are to one of the poles, the more days after that would continue to be dark around the clock, for the next 3 months. Eventually, after that number of days, you'd begin to have daylight, very short at first, but getting longer and longer for the rest of the 3 months. After 9 months total, every place on Earth would have 12 hours of daylight and 12 hours of darkness. For the next 3 months, your hours of daylight would increase, while on the other half of the Earth, the hours of darkness would increase. After a full year, your half of the Earth would have 24 hours of daylight again, and the other half would have 24 hours of darkness again, and the whole thing would repeat for the next year. Climate-wise . . . Wherever you are, your weather would get warmer and warmer during the part of the year when you have more than 12 hours of daylight, level off when you start having nights, and start getting cooler and cooler when you start having more than 12 hours of darkness. On the equator, the sun would oscillate between the zenith and the horizon twice annually, and would never set. So I expect the warmest climate would still be in a band around the equator. At each pole, the sun would be above the horizon for a solid 6 months, and then below it for a solid 6 months, just as it is now. But instead of taking 3 months to crawl 23.5° up from the horizon and the next 3 months to droop back to the horizon, the sun would zip from the horizon to the zenith in 3 months, and then take another 3 months to return to the horizon. I'm thinking that this would bake the poles mercilessly for half the year, and freeze them utterly for the next 6 months, so that, besides having the lowest average annual temperature, the polar regions would also have by far the widest extremes of temperature, and would be the harshest, most lifeless places on Earth, and would make today's polar climate look like a lush garden in springtime by comparison.


Why does Antarctica get 24 hours daylight in December and 24 hours darkness in June?
