Both are theoretically the same. It depends on the accuracy of your measurements and the method of measurement. Are you measuring at exactly theoretical sea level or up and down mountains and valleys (along the sea floor?) etc. I do believer that the Earth is slightly larger south of the equator and so the Antarctic circle could be larger.
Both are polar and both mark geographies beyond which there is at least one 24-hour period each year with no sunrise or sunset.
The difference is the location of each, one north of the equator and the other south of it.
They're the same distance from the equator but in opposite directions. The Arctic Circle
is at North 66.4 degrees and the north pole is at its center. The Antarctic Circle is at
South 66.4 degrees and the south pole is at its center.
Both circles mark the farthest from one of Earth's poles you can get and still have
at least one 24-hour period of no sunrise and one 24-hour period of no sunset
during the year. The phenomenon occurs north of the Arctic Circle and south of
the Antarctic Circle.
antarctic circle is colder than arctic circle
Yes. On average the Antarctic is colder than the Arctic.
On average, the Antarctic Circle.
No.
On average, yes.
The antarctic is colder than the arctic because of Antarctica, the continent, on which is stored 90% of the Earth's store of ice.
No, it's not.
There is a continent south of the Antarctic Circle, while the Arctic Circle surrounds sea ice.
Yes, by about 30 degrees F. This is because there is a continent in the Antarctic and there is only sea ice in the Arctic.
No. Boston, Mass in the USA is closer to the Arctic Circle than to the Antarctic Circle. Boston and the Arctic are both in the Northern Hemisphere: Antarctica is in the Southern Hemisphere.
Because the antarctic region is colder than the arctic and the Polar bear won't get the warmth it needs.
Warmer
Yes.
the subarctic is colder than the tundra
The UK is the closer.
The continent of Antarctica is in the Antarctic, storing 90% of the earth's store of ice. It is about 30 degrees F colder in Antarctica than in the open water of the Arctic ocean. Antarctica is a continent surrounded by the Southern Ocean. The Arctic is open water -- the Arctic ocean -- surrounded by land.
