Ablation zone — On a glacier, the ablation zone, zone of ablation or zone of wastage is the area in which annual loss of snow through melting, evaporation, iceberg calving and sublimation exceeds annual gain of snow and ice on the surface. Of these, melting is… … Wikipedia
Fluvioglacial landform — Fluvioglacial landforms are landforms moulded by glacial meltwater. This discharge of glacial streams, both supraglacial and subglacial, is higher in the warmer summer months. As the water often flows under pressure, it has a high velocity and is … Wikipedia
