A glacier is a massive, slow-moving body of ice that forms from accumulated snow over many years. These ice giants are found in polar regions and high mountains, where temperatures remain low enough for the snow to compact and transform into ice. Glaciers play a crucial role in shaping landscapes through erosion and sediment transport. As glaciers move, they carve valleys and create unique geological features. They are also vital indicators of climate change, as their retreat can signal rising global temperatures. Protecting glaciers is essential for maintaining ecosystems and freshwater resources for millions of people worldwide.
