Snowfall is made up of both single ice crystals and clumps of ice crystals. The clumps are called … Web8 apr. 2024 · Snow begins as ice crystals, which nucleate from the chance aggregation of water molecules into stable ice-like structures called ice embryos. Nucleation can occur either homogeneously or heterogeneously. In the latter process, crystals nucleate onto the surfaces of ice nuclei, which serve to lower the free energy barrier to ice formation.
