Crystalline structure of snow
WebSnow is precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes.Since it is composed of small rough particles it is a granular material.

WebCrystal Faceting ... How snow crystals form sharp edges and flat faces ... When water freezes into ice, the water molecules stack together to form a regular crystalline lattice, and the ice lattice has six-fold symmetry (see the Primer). It is this hexagonal crystal symmetry that ultimately determines the symmetry of snow crystals. WebIce, like many solid materials, forms a crystalline structure. In the case of water, the crystalline structure may be attributed to the hydrogen bond, a special kind of an attractive interaction. So a big chunk of ice will have a …

It’s the organized structure taken by most minerals. Apatite, for example, forms six-sided crystals. The mineral crystals that make up rock are usually too small to be seen with the unaided eye.
WebIt involves two processes: intracrystalline gliding, in which the layers within an ice crystal shear parallel to each other without destroying the continuity of the crystal lattice, and recrystallization, in which crystal boundaries change in size or shape depending on the orientation of the adjacent crystals and the stresses exerted on them. WebIce crystals are "minerals" because they are naturally occurring solids with a definite chemical composition and an ordered internal structure.
