Glacier

The video explains glaciers as large, slow-moving ice masses, detailing two types: alpine and continental. Alpine glaciers flow from mountains into valleys, while continental glaciers cover vast areas, forming ice shelves and icebergs. Glaciers form from compacted snow and are the largest freshwater source. They reshape landscapes by grinding and depositing rocks, creating features like moraines.
