Boundaries between the continents of Earth Zemlya extend northward from the northern end of the Ural Mountains and are a continuation of that chain into the Arctic Ocean. While Novaya Zemlya was variously grouped with Europe or with Asia in 19th-century maps it is now usually grouped with Europe, the continental boundary considered to join the Arctic Ocean along the southern shore of the Kara Sea. The Russian Arctic archipelago of Franz Josef Land farther north is also associated with Europe. Europe ends in the west at the Atlantic Ocean, although Iceland and the Azores archipelago (in the Atlantic, between Europe and North America) are usually
Severnaya Zemlya expands its large delta, lies to the east of Severnaya Zenlya. The topographic relief of the archipelago is quite smooth, with Neoproterozoic and Palaeozoic sedimentary successions dominating its bedrock geology. Glaciers in the archipelago have a characteristic dome shape with a continuously decreasing surface towards their edges. Ice cliffs are found only at the base. The places where the glaciers reach the sea contribute to the formation of icebergs. The most active glacier fronts are the eastern side of the Academy of Sciences Glacier at Krenkel Bay as well as its southern side. Another quite active glacier is the Rusanov
