  • Geography - glaciers
    • Slow-moving rivers of ice
    • Formed in upland areas where snow accumulates to over 15m deep
    • Snow compressed to form ice (firn)
    • End of glacier is a snout
    • Gravity causes glaciers to flow downhill - 30cm a day
    • Crevasses are deep cracks in a glacier
    • Glacial surge is a rapid advance of a glacier - 10-100m a day
      • Caused by a build-up of meltwater which reduces friction
