Transcript of How Do Snowflakes Form?

Is Snow Really White?
Snow is actually not white. The sun is white and when the sunlight is absorbed uniformly over the wavelengths of visible light, snow gives its appearance as white.
Snowflake Designs And Snow
Heavy snowfalls are called snowstorms. Blizzards happen with snowstorms with very strong winds. Light and fluffy snow is often called powder. Snowflakes come in different shapes and sizes and are completely different to the next. They have a geometrical shape made of 5 points.
The Smallest Snowflakes
The smallest snowflakes are called diamond dust crystals. They might be as small as the diameter of human hair. They got their name by how the crystals sparkle in the sunlight as they float through the air.
How Do Snowflakes Form?
Snow forms in clouds when the temperature is below freezing point. Water droplets freezing on small ice particles create them. Snowflakes are made of crystals of ice that form from bits of dirt in the air. An ice crystal drops through the cloud and bumps into other snowflakes and becomes one. It takes about 15 to 45 minutes for a snowflake to form and fall to the ground. This process creates the snowflake’s complex design.
