On a Christmas card a relative sent today was this sentiment: " Maybe snowflakes are letters God uses to write upon the winter sky - a graceful script of peace, hope, and love." That is such a lovely thought.
Snowflakes or snow crystals form when ice crystals freeze around tiny particles of dust that are in the air and join together as they fall. Ice crystals that melt as they fall become rain. Ice crystals that form near the ground are called frost.
