On the sliding of glaciers
WebGlaciers move as a result of deformation inside the glacier or sliding at its base, and its downhill movement is resisted by stress and friction at the base and sides of the glacier. The size of a glacier is maintained by … WebBasal sliding is the act of a glacier sliding over the bed due to meltwater under the ice acting as a lubricant. This movement very much depends on the temperature of the area, the slope of the glacier, the bed roughness, the amount of meltwater from the glacier, and the glacier's size. The movement that happens to these glaciers as they slide ...
