What is a gletsjer?

Answer 1

A glacier is a large mass of ice that forms from the accumulation and compaction of snow over many years. It moves slowly under its own weight, flowing like a river of ice, and can shape the landscape through erosion and sediment deposition. Glaciers are found in polar regions and high mountains, playing a crucial role in Earth's climate and water supply. They are sensitive indicators of climate change, as their size and health are affected by temperature and precipitation patterns.
