Web3 apr. 2024 · Glaciers and lakes are intrinsically connected. Lakes form when meltwater ponds, and this can happen on the ice surface (supraglacial lakes), in front of the ice (proglacial lakes), or even underneath the ice (subglacial lakes). Glacier lakes can affect ice flow by reducing friction at the ice-bed interface, encouraging basal sliding. Web24 sep. 2024 · Glaciers and the Ice Age. A glacier is created when ice crystals are packed tightly together as layers upon layers of snow build up. When the ice stays in place for more than a few years, it is called a glacier.
