These two lines of latitude mark locations on Earth beyond which there is at least one 24-hour period with no sunrise/ sunset per year.
No. The circles are circles. The poles are points. If the circles were points, then they might be called the Arctic and Antarctic Poles, but they wouldn't be called the Arctic and Antarctic Circles since they would be only points.
Polar Zones
Latitude maps include both the Arctic and Antarctic Circles.
Beyond both circles, there is at least one 24-hour period of no sunrise, sunset annually.
Although circles don't have beginnings or endings, they can be found at 66.5622 degrees north and south latitudes, respectively.
67 degrees i think.
roughly 1700 miles
66.5622 degrees north and south
The Arctic circle is 66 33′ 39″ north and the Antarctic is the same south of the equator.Every longitude crosses both circles.
There are many things which completely circle the globe. The first thing that comes to mind is the equator, but the artic and Antarctic circles also circle the globe (as well as every other degree of latitude). The taiga forest circles the globe. The atmosphere circles the globe.
66.5622 degrees north and south respectively.
The question doesn't specify from which starting point. The Arctic and Antarctic Circles are roughly 23.5 degrees from the north and south poles respectively, which is roughly 1,620 miles (2,608 km).
