At depths of greater than 60 m,ice moves by plastic deformation.What causes this transition from brittle to ductile behavior?

Question

Quizplus · Accepted Answer

At depths greater than 60m, the pressure exerted on the ice becomes so high that it allows for limited deformation, leading to plastic behavior. This is because under high pressure and low temperatures, the ice crystals begin to deform by rearranging themselves around defects, rather than breaking apart. This results in a more ductile behavior. The other options are not supported by scientific evidence and do not explain the transition from brittle to ductile behavior.
