Why is snow a crystalline solid?

Answer 1

yes, each snowflake is one dendritic ice crystal.

However fallen snow is not a solid, the snowflakes have stacked up to capture a larger volume of air than the volume of the snowflakes themselves.

Answer 2

Snow is a crystalline solid because its water molecules arrange themselves in a repeating, geometric pattern when they freeze. This arrangement results in a highly organized structure with a defined shape and symmetrical properties, characteristics of a crystalline solid.
