Which outcome happens because hydraulic head difference increases?

💡 Explanation

Faster glacier basal sliding happens because increasing hydraulic head differences enhance regelation at the ice-bed interface. This regelation, a phase change driven mechanism, decreases friction along the bed therefore basal sliding accelerates notably, rather than weathering, sublimation, or vegetation changes being the primary outcome.
