The Arctic does not belong to any single continent. It is a polar region defined by the Arctic Circle (66.56°N) and characterized by the Arctic Ocean surrounded by landmasses.
Arctic Council (8 states + 6 indigenous permanent participants) coordinates cooperation. No sovereignty over Arctic Ocean seabed beyond EEZs (UNCLOS).
The Arctic Ocean sits on the Eurasian and North American plates. Lomonosov Ridge divides it. Continental crust underlies the shelves; oceanic crust in deep basins.
The Arctic is a shared planetary system—climate regulator, indigenous homeland, geopolitical frontier—not a continent.
