Accumulation, Ablation, andIce Flow

The life cycle of a glacier is governed by the balance between accumulation—the addition of snow and ice—and ablation, which includes melting, sublimation, and calving. Accumulation occurs primarily in the higher elevations where snowfall exceeds melting, allowing snow to compact into firn and eventually glacial ice. This dense ice mass flows downslope through internal deformation of ice crystals and basal sliding over the bedrock.
