In a glacier the ice moves fastest:
WebA steeper gradient enables faster movement of the glacier, less steep gradients lead to slower movements. It’s important to note that gravity and weight are the fundamental causes for glacial movement as without it none of the other factors would be relevant and there would be zero glacial movement. Lithology WebApr 12, 2024 · Abstract. Fast glacier flow and dynamic instabilities, such as surges, are primarily caused by changes at the ice-bed interface, where basal slip and sediment deformation drive basal glacier motion. Determining subglacial conditions and their responses to hydraulic forcing (e.g. rainfall, surface melt) remains challenging due to the …

Ice deforms because it is plastic.
