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. It has an open and therefore soft structure, unless packed by external pressure.. Snow is commonly formed when water vapor undergoes deposition high in the atmosphere at a temperature … Snowflakes nucleate around mineral or organic particles in moisture-saturated, subfreezing air masses. They grow by net accretion to the incipient crystals in hexagonal formations. The cohesive forces are primarily electrostatic. In warmer clouds, an aerosol particle or "ice nucleus" must be present in (or in contact with) the droplet to act as a nucleus. The particles that make ice nucle…
