4. How does ice formation start?

  • the mass changes colour from white, indicating the presence of air, to a bluish colour, indicating that the air has been largely expelled.
  • Te snow accumulates, compression by the upper layers gradually turns the lower snow into a more compact form known as firn or neve.
  • Snow falls as flakes, which have an open, feathery structure that traps air.
  • air is progressively squeezed out of the lower snow by the weight of the upper layers and after a period of some years a mass of solid ice develops – where there is no summer melting, this process takes longer.
  • Meltwater seeps into the gaps and then freezes – further compacting the mass.
