3. How does ice formation start?
- Snow falls as flakes, which have an open, feathery structure that traps air.
- Te snow accumulates, compression by the upper layers gradually turns the lower snow into a more compact form known as firn or neve.
- the mass changes colour from white, indicating the presence of air, to a bluish colour, indicating that the air has been largely expelled.
- Meltwater seeps into the gaps and then freezes – further compacting the mass.
- 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.
