Ecosystems: Holes in Glaciers

The video discusses Antarctica, the coldest continent, and its significance for geographical research. It explains glaciers, which cover 10% of the Earth's surface, and focuses on cryoconite holes formed by dust on glaciers. These holes can lead to faster glacier movement, linking to climate change. The video also explores the distribution patterns of these holes, emphasizing the importance of understanding geographical distributions.
