North of the Antarctic Circle, geographies experience a mix of hours of sunlight and hours of no sunlight.
At the Antarctic Circle, there is at least one 24-hour period of no sunrise/ sunset per year. At the Equator, these periods are about 12 hours each.

Mid-latitudes
I'm sure that is the Antarctic Circle.
Those are the "polar" regions.
North of the arctic circle, or south of the antarctic circle, but only at certain times of the year.
"High" latitudes. The equator has a latitude of zero. The area between the Tropic of Cancer (at 23.5 degrees north) and the Tropic of Capricorn (at 23.5 degrees south) are the "tropics" or low latitudes. The "polar regions" are above the Arctic Circle or below the Antarctic Circle, where the latitudes are higher than 66.5 degrees (north or south) are "high". The areas between the tropics and the arctic/antarctic are called "mid-latitudes or "temperate zones".

The imaginary line that forms the northern boundary of most of Antarctica is the Antarctic Circle, located at approximately 66.5 degrees south latitude. Beyond this line, there are restrictions on sunlight and daylight hours due to the tilt of the Earth's axis.
Antarctica has the highest number of latitudes, as it spans from the South Pole at 90 degrees south to the Antarctic Circle at 66.33 degrees south.
The Tropic of Cancer is to the Tropic of Capricorn as the Arctic Circle is to the Antarctic Circle. They are lines of latitude either north (Arctic Circle, Tropic of Cancer) or south of the equator.
They are called the middle latitudes, and include mostly regions with temperate climates.
