What heat belt does Antarctica belong to?

Antarctica belongs to the Earth’s Polar Belt, the coldest, here the temperature drops from -60 to -80 degrees Celsius. Also, a great feature of this belt is the Polar Day, where in the summer the sun does not set for six months, and in the winter, on the contrary, there is no sun. Another feature of the poles is that the Earth has a tilt, and therefore, when it is day at the North Pole, it will be night at the South Pole. In addition to all this, residents of the Arctic Circle can observe such a phenomenon as the Northern Lights.
