Basal sliding

  "id": "MLC-T-MET-003841",
  "term": "Basal sliding",
  "field": "Meteorology and atmospheric science",
  "definition": "The movement of a glacier or ice sheet over its bed, lubricated by a thin layer of meltwater at the ice-bedrock interface. This water reduces friction, allowing the ice mass to slip forward as a coherent block. Basal sliding is a primary mechanism of motion for temperate glaciers, where the temperature at the base is at the pressure melting point.",
