Glacial movement refers to the slow flow of ice within a glacier, driven by gravity and the weight of the ice itself. As temperatures rise, the base of the glacier can melt slightly, creating a thin layer of water that allows the glacier to slide over the ground. This movement can occur in different ways, including internal deformation and sliding at the base. The speed of glacial movement varies, with some glaciers moving just a few centimeters per year, while others can advance several meters in a day. Factors influencing this movement include the slope of the land, the thickness of the ice, and the temperature. Understanding glacial movement is crucial for studying climate change and its impact on sea levels.
