WebJan 30, 2024 · 1. Definitions. A certain amount of confusion exists in the classification of metamorphosed snow. For example, the term crystalline, which is a precise, scientific term, is misused by many workers in the field. A solid is crystalline if its atoms are arranged in an orderly array. Under this definition, all ice found in nature is crystalline whether it … Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals … See more Snow develops in clouds that themselves are part of a larger weather system.
