The geographical term for a large body of ice moving slowly down a slope is a glacier. Glaciers form over centuries from accumulated snow that compacts into ice. As they grow, glaciers creep downwards due to the pull of gravity. They play a critical role in shaping landscapes through processes like erosion and deposition. Glaciers are found in polar regions, such as Antarctica and Greenland, as well as in mountainous areas worldwide. As climate change affects their stability, studying glaciers provides insight into global warming and its impact on sea levels and ecosystems.
