At a depth of 50 meters a glacier is solid and very brittle. At depths that are deeper than 50 meters, glaciers develop plasticity due to the pressure applied to it from the ice above.

Below about 40 meters the pressure of overlying material causes the ice to behave in a ductile manner, meaning that it will stretch and bend rather than fracture.

Below 50 meters, the ice now behaves in a ductile manner rather than a brittle manner, meaning it will stretch and fold under stress rather than fracturing.
