Glaciar

This video tutorial explores glaciers, defining them as large, slow-moving rivers of ice, rock, and dust. It distinguishes between two types: alpine glaciers, which flow from mountain peaks to valleys, and continental glaciers, which are massive ice sheets covering large areas. The video explains how glaciers form from compacted snow layers and describes their movement, which reshapes landscapes by eroding and depositing materials. It also covers the formation of ice shelves and icebergs from continental glaciers.
