snowflakes

and speaking of.....Snowflakes. Snowflake Birth: 1. Rising air, moisture and cold temperatures combine to form snowflakes in clouds high above the earth. First, water droplet freezes into ice crystal. 2. If temperature is near 5 degrees Fahrenheit and plenty of moisture is present, crystal grows six branches with arms. 3. Crystal grows heavier as moisture condenses onto it. 4. Crystal continues growing as it falls through the cloud. 5. Crystals falling into warm air begin melting. Water can act like glue, holding crystals together in large flakes. Provided by Reference.com
