Snowflakes! They arrive in flurries, storms and blizzards, not to mention “Winter Bomb Cyclones!” I’ve always thought the science behind snowflakes is amazing.
A snowflake begins when a tiny dust or pollen particle comes into contact with water vapor high up in Earth’s atmosphere. The water vapor coats the tiny particle and then freezes into a tiny crystal of ice. This tiny crystal will be the “seed” from which a snowflake will grow. The process is called crystallization.
