What are two landmasses that are mainly found in the north polar zone?

The two main landmasses found in the north polar zone are Greenland and the Arctic Archipelago. Greenland, the world's largest island, is predominantly covered by ice and is situated between the Arctic and Atlantic Oceans. The Arctic Archipelago, which includes numerous islands such as Baffin Island and Ellesmere Island, is located north of the Canadian mainland. Both landmasses are characterized by their harsh, cold climates and extensive ice coverage.
