Arctic definition. Region in the northernmost area of the Earth, centered on the North Pole. Note: The weather of the Arctic is characterized by long, cold winters and short, cool summers. Note: The Arctic has been the object of much exploration by air, land, and sea. The shortest distance by plane between continents in the Northern Hemisphere is often over the Arctic.
The region surrounding the North Pole consists of a large ocean surrounded by land. This ocean, called the Arctic Ocean, is like no other ocean on Earth; and because of its special location and climate, the lands that surround it are unique.his map shows three definitions of the Arctic: the tree line; the 10 degrees Celsius isotherm, and the Arctic Circle at 66Â° 32 North.
