GeographyTopographic Features
Much of the Arctic coastline is marked by broad, flat tundra, which means the wind blows nearly continuously because the flow is largely unobstructed. The West Siberian Plain and Central Siberian Upland cover a large part of the Russian Arctic and are primarily tundra.
However, some areas are marked by well-defined topography, including the sea cliffs and deeply incised fjords of Norway, Greenland, and the Canadian Arctic Archipelago.
Prominent mountain ranges include the Brooks Range of Alaska, the Arctic Cordillera of Canada, and the Scandinavian Mountains. The summit of the Greenland ice sheet reaches over 3000 m (~10,000 ft).
