The icy region surrounding the Arctic Circle is commonly referred to as the Arctic. This region experiences extreme climatic conditions, characterized by long, harsh winters and short, cool summers. The Arctic is home to a diverse range of wildlife, including polar bears, seals, and various migratory birds, as well as unique ecosystems such as tundra and sea ice. The Arctic Circle itself is defined as the latitude at which the sun does not set during the summer solstice and does not rise during the winter solstice, leading to phenomena like the Midnight Sun and Polar Night.
