Glaciers are large bodies of ice that form over long periods of time when snow accumulates and compacts into ice. They are found in areas with cold temperatures and high snowfall, such as polar regions and high mountains. Glaciers are important indicators of climate change, as changes in their size and movement can be used to track shifts in temperature and precipitation patterns. They also play a crucial role in shaping the landscape, as they erode rocks and carve out valleys as they move. Research in this area focuses on understanding the behavior of glaciers, their impact on the environment, and how they are responding to changing climate conditions.
