   How do snowflakes form?

   • First of all, the temperature and humidity of the atmosphere determine the shapes of snowflakes. And snowflakes form in the atmosphere when cold water droplets freeze onto dust particles. Finally, depending on the temperature and humidity of the air where the snowflakes form, the resulting ice crystals will grow into a myriad of different shapes.

   Why are snowflakes small and delicate?

   • Snowflakes are small and delicate, because they are limited by the amount of water vapor surrounding them as they grow in the atmosphere. The crystals often grow in fractal and jagged patterns. Ice cubes formed in the freezer are made of many tiny ice crystals that formed quickly and grew into each other.

   What is a snowflake?

   • A snowflake is a more general term; it can mean an individual snow crystal, or a few snow crystals stuck together, or large agglomerations of snow crystals that form ‘puff-balls’ that float down from the clouds.” A few facts about snow crystals: They are formed from water vapor that condenses directly into ice inside of clouds.

   Do snowflakes form the same way?

   • Given slight changes in temperature and humidity and the huge number of molecules and bonding opportunities involved, the ice structures created can be incredibly diverse and complicated. For this reason, it is entirely likely that no two snowflakes form in exactly the same way, and consequently no two snowflakes are alike.

   Why did scientists try to find snowflakes?

   • In a way, it was a heroic effort,” said Dr. Pamela Henson, the Smithsonian’s historian. Before Bentley, scientists struggled to closely examine snowflakes because the crystals were hard to isolate and melted so quickly.

   Wilson Bentley (1865–1931) from Jericho, Vermont, was the first person to capture photographs of snowflakes through a microscope attached to a camera. His collectionof over 5,000 images – no two alike – introduced many people to the astounding diversity of snow crystals.

   In 1951, scientists from an organization now called the International Association of Cryospheric Sciences (IACS) devised a classification system that characterized snowflakes into 10 basic shapes. Kenneth Libbrecht, professor of physics at the California Institute of Technology, in his guide to snowflakes at SnowCrystals.com, provides this chart of...

   Libbrecht has made extensive observations of how water molecules get incorporated into snow crystals. In his research, he observed that the most intricate snowflake patterns form when there is moisture in the air. Snowflakes produced in drier conditions tend to have simpler shapes. According to Libbrecht’s research, temperature also has a large eff...
