WebJun 22, 2024 · If the glacier flows just by internal deformation, then it is likely that rates of creep decrease with depth, with fastest ice movement at the surface and slowest (or no) ice movement at the base and at the valley sides, where resistive stresses are highest (Jiskoot et al., 2011). Ice deforms because it is plastic. WebTwo students are discussing which way glacier ice moves when a glacier is shrinking Student 1: Glacier ice always flows downhill because of gravity, and A shows the ice flowing downhill. The glacier shrinks because it melts faster than the glacier is flowing. WebGravity is the cause of glacier motion; the ice slowly flows and deforms (changes) in response to gravity. A glacier molds itself to the land and also molds the land as it creeps down the valley. Many glaciers slide on their beds, which enables them to move faster. cancer research fashion show
