High pressure
It takes the weight of that much ice to cause the plastic flow.
It takes the weight of that much ice to cause the plastic flow.
Plastic flow in ice occurs at depths greater than 50 meters because at this depth, the pressure from the weight of overlying ice causes the ice to deform and flow like a plastic material rather than behaving brittle like at shallower depths. This deformation is due to the combination of high pressure and temperature causing the ice to exhibit ductile behavior.

High pressure
Because metal and plastic arent the same materials so metal goes with the flow through static electricity but plastic cant.

When a glacier moves by internal plastic flow, the basal layers, particularly those close to the glacier bed, tend to move faster than the upper layers. This is due to the increased pressure and heat at the base, which causes the ice to deform more readily. Additionally, the flow is often faster in the center of the glacier compared to the edges, as friction with the valley walls slows down the flow.
