Arctic Circle
The Arctic Circle is a major circle of latitude located at 66.5 degrees north of the equator. It defines the polar region and marks the southernmost point of the polar day and polar night during the June and December solstices respectively.

- Canada
- Iceland
What degrees north latitude marks the boundary of the Arctic Circle?
Approximately 66° 33' 39" N marks the boundary of the Arctic Circle
What continent is in the eastern and western hemisphere and also touches the Arctic Circle?
The continent of Eurasia (commonly divided into Europe and Asia) extends through both the Eastern and Western Hemispheres, all the while touching the Arctic Circle.
Which country is called land of the midnight sun?
country- Norway
state- Alaska
continent- Antarctica
this name can be applied to any country on or near the arctic circle where the sun remains near visible at local midnight. A quarter of Finlands territory is located north of the Arctic circle and they 'enjoy' 73 days when the sun does not set during summer. Other countries are northern Canada, Alaska, Greenland, Norway, Sweden and Russia. At North Cape, Norway 'daylight' extends from 14th May until 29th July. On the Svalbarg archipelago, further north, daylight extends from 20th April to 22nd August
The midnight sun refers to areas of the arctic region that receive 24 hours of sunlight/night for months at a time. Though no country is really known as the midnight sun, areas of the US, Canada, Russia, Sweden, Finland, Norway, and Denmark experience such.
Land of the Midnight Sun refers to northern regions in the world like Canada or Alaska, as well as Russia and Norway
Portions of many countries above the Arctic Circle. Includes Norway, Sweden, Russia, Alaska, Northern Canada, Greenland, Iceland, Lapland, etc.
How long does it take by boat to get to the Arctic Circle?
That can't be answered precisely if you don't specify a starting point.
Which current brings cold water from the Arctic Circle southward?
The Labrador Current (aka Arctic Current) brings cold water down the east coast of Canada, through the Grand Banks to Nova Scotia. It extends from the Baffin Island Current, where Baffin island is partly within the Arctic Circle.
What current brings air from the arctic circle southward?
The polar jet streams are circulating air currents around the poles. In the Northern Hemisphere, the jet stream carries air eastward, and can transport Arctic air southward from the north polar vortex into the lower latitudes.
What is where most of US is located called between the Arctic Circle and the Tropic of Cancer?
The continent of North American is located between the Arctic Circle and the Tropic of Cancer.

Both:
- Killer whales can tackle elephants, seals, sting rays, dolphins, sharks and full grown whales
- Both places inhabit seals
- Both places rely on krill
- Both places have whales and birds
Arctic:
- In the Arctic there are polar bears
- In the Arctic there are reindeers and wolves
- It has Arctic foxes
- Whales come annually for the scrub
- There are vast colonies of birds in the Arctic
- The Arctic does not have any penguins
- The Arctic has amphibious animals however Antarctica does not.

How many hemispheres is the arctic ocean located?
The Arctic Circle is located in three different hemispheres; The Northern Hemisphere, Western Hemisphere, and the Eastern Hemisphere.
What states does the Arctic Circle pass through?
The Arctic Circle passes through the US state of Alaska.
Alaska
What is the size of the Arctic Circle What is the diameter or length width?
Length or circumference of the Arctic / Antarctic Circle.
This depends on the time, date, and whether the calculations are made using True or Mean obliquity of the ecliptic.

To calculate the latitudes I used the PHP Science Labs website, Obliquity of the Ecliptic and Nutation in Obliquity calculator (for True using the IAU 2000B series), and for the distances Charles Karney's RhumbSolve online rhumb line calculator.
In an email to me from Charles Karney: "The accuracy of 15 nanometers that I quote is for paths up to half-way round the earth."
True obliquity of the ecliptic is used to calculate the latitudes of the Arctic Circle, sent to me from the National Land Survey of Finland, the Finnish Geodetic Institute, calculated the latitudes sent to me, for every ten days, for the years 2000-2049. The GIT Barents website (which is now the Aboriginal Mapping Network, and has been totally altered), had on it the following: "the circle has in 2006 passed the peak of the motion wave: Until the year 2015 the Arctic Circle will travel again 700 metres to the north, and after that it will continue to the south about 450 metres during the following nine years. Depending on the phase of the motion, the Arctic Circle can move over three metres a day and over 100 metres a year!"
This was obviously also calculated using True obliquity of the ecliptic.
In my opinion true obliquity of the ecliptic should be used. Since true obliquity is the actual, hence "true". Mean obliquity of the ecliptic is only obviously the mean, and is in my opinion, just for the convenience of humans. Since when for example using mean obliquity of the ecliptic for the Arctic Circle, it supposedly will only move north at an equal, regular rate, for about the next 10,000 years. Which makes for far easier calculations of the latitudes. Mean is just that, only the mean movement. In my opinion, the Arctic Circle is actually moving mostly north but sometimes south, for about the next 10,000 years, and it moves in a seemingly random, unpredictable manner (true obliquity of the ecliptic). Of course this would mean, that Antarctic Circle is moving mostly south, but sometimes north, for about the next 10,000 years. The Swedish National Land Survey or Landmäteriet website has an Arctic Circle latitude calculator, that calculates in both mean and true obliquity of the ecliptic. However it only gives two latitudes for each year, one for mean obliquity, the other for true obliquity. For 2016, Mean obliquity 66° 33' 46.07" N, True obliquity 66° 33' 54.92" N. Using the PHP Science Labs website, Obliquity of the Ecliptic and Nutation in Obliquity calculator, True obliquity 66° 33' 54.92" N is at least closest to 3 March, and Mean obliquity 66° 33' 46.07" N is closest to 24 January.
