Is it true that Alaska never has night?Explain this if the earth rotates.?

Answer 1

For Alaska south of the Arctic Circle (99% of our population), the summer and winter lighting is like the rest of the northern hemisphere (longer summer days, longer winter nights) but much more extreme.

Here, 60 air miles southwest of Anchorage, we get 19.5 hours from sunrise to sunset on June 21. And 5.5 hours on December on Dec 21.

At the Arctic Circle (lattitude 66.33 degrees North), by definition, they get one day of continous light on June 21st. As you go further north, that period of continous light (and dark in the winter) gets longer. On the shore of the Arctic Ocean (Barrow, Prudhoe Bay), continuous light lasts for about 3 months. The newspapers in the state report "The sun went down in Barrow today for the last time in 87 days", etc.

Demonstrate this to yourself by spinning a ball (or better yet, a globe of the Earth) in the sunlight. With the Earth most tipped away from the Sun, a 23 degree tip, the Arctic Circle will be, exactly, the area always in shadow.

Answer 2

sigh..it scares me to think what they are not teaching in science and geography.

The tilts on it's axis, in the spring and summer, due to the position of earth in it's orbit around the sun, the north pole is pointing towards the sun. Due to the extreme northern latitude of Alaska, it is exposed to the sun through a 24-house rotation. It does get a little dark, more like a twilight darkness.

Get a globe and visualize it.

By the way..this is why it is winter in Australia when it is summer in the US.

Answer 3

No it's not true. Alaska has nites, just different times than the rest of us in the lower 48. In the winter they don't have much daylite, the approximate dates are June 22 for the longest daylite hours and 6 mo. later on Dec.22, they have the longest nite or dark time. around Fairbanks, they get close to 22 or more hours of daylite and then it turns to dusk, sort'a like here in the lower 48 just after the sun begins to set. In the winter about Dec. it has mostly dark except for a little bit of twilite. I hope this helps, I have 2 kids who live in AK.

Answer 4

Since the Earth's axis is tilted with respect to the ecliptic by approximately 23 degrees 26 minutes (commonly rounded to 23 degrees and a half), the sun does not set at high latitudes in (local) summer. The duration of the midnight sun increases from one day during the summer solstice at the polar circle to approximately six months at the poles. At extreme latitudes, it is usually referred to as polar day. The length of the time when the sun is above the horizon varies from 20 hours at the Arctic Circle and Antarctic Circle to 186 days at the poles.

Answer 5

No, for a good part of the year Alaska (the part of it above the arctic circle) is all daylight...then, for another part of the year, it's all darkness...this is because it's so far north that depending on the earth's tilt the sun may or may not be hitting it at all hours of the day.

Answer 6

incorrect- it has to do with the tilt of the earth. during the summer (in the northern hemisphere) the earth tilts toward the sun. because of Alaska's proximity to the pole it doesn't get fully dark at night. In the winter on the other hand it very little light in the day (similar to twilight)

Answer 7

Parts of Alaska ar near the top of the earth, the earth tilts toward the sun in summer, away in winter.

Answer 8

No not true....they have like 6 months of light and 6 months of darkness

Answer 9

Answering this question capability stereotyping. many of the component would nicely be authentic for some for a while. no longer unavoidably all factors would be authentic for all women persons all time. for this reason, it extremely is a competent question yet admire lady as she is is the respond.

Answer 10

this should help you understand their double daylight savings time.
