The geographical feature that is a large, slow-moving body of ice is a glacier. Glaciers form from the accumulation of snow over many years, compaction, and recrystallization, resulting in massive ice formations. They are primarily found in polar regions and mountainous areas. Glaciers play a critical role in the Earth’s climate system, influencing sea levels and serving as freshwater reservoirs. The study of glaciers is crucial for understanding climate change and its impact on the planet.
