Basically, the Polar Regions are Antarctica and the Arctic. Althought these are not entirely the poles, these are the apporxiamate area of where they are. The Arctic Circle is the latitude where the sun doesn't set at the summer solstice, which is 66° 33' N.
| Antarctica is located in the Antarctic region of the Southern Hemisphere, and it is nearly entirely south of the Antarctic Circle. It is completely surrounded by the Southern Ocean (a.k.a. the Antarctic Ocean).
