Why do continental glaciers flow?
Glaciers flow by internal plastic deformation when the weight of overlying ice, firn, and snow causes ice crystals at depth to arrange themselves in parallel layers that glide over each other. This deformation happens when a threshold pressure from the overlying mass is exceeded. Pressure is greater under thicker accumulations of ice, so continental glaciers flow radially outward from central areas of thicker ice to marginal areas of thinner ice.
