Perito Moreno Glacier

Diagram showing a mountain glacier collapse in which melting ice destabilizes rock, triggering a rockslide that changes the ice into water to flood the valley below with water, mud, and debris.

Map of Antarctica showing major geographic regions such as West Antarctica, East Antarctica, Queen Maud Land, Wilkes Land, Victoria Land, Marie Byrd Land, and Ellsworth Land. The map also marks prominent research stations operated by various countries around the continent's coast and interior, as well as nearby seas including the Weddell Sea, Ross Sea, Amundsen Sea, and Bellingshausen Sea. Surrounding oceans-the Atlantic, Indian, and Pacific-are labeled.

The island is dominated by the Greenland Ice Sheet, with coastal settlements such as Nuuk, Upernavik, and Kangerlussuaq marked. Neighboring bodies of water include Baffin Bay, the Labrador Sea, Greenland Sea, and Denmark Strait. An inset globe highlights Greenland's location in the northern Atlantic.
