Why Snowflakes Are Always Flat

Why Snowflakes Are Always Flat

Have you ever saw that frozen water molecule despite maintaining the ability to grow in 3D directions prefer taking a 2D shape? Snowflakes are cool to look at, right? Each snowflake is different, but typically they all are crystals experiencing growth in 3D space. This indicates that they can grow in any direction, but they are flat everytime.

Why is that happening? Why are snowflakes always 2D? A video from the YouTube channel SciShow describes the phenomenon and says, ‘It all comes down to how ice crystals form on the molecular level.’ The video is made to describe snowflakes and tells the entire process in an easy to understand style.

The video explains that a snowflake determines its growth shape based on temperature. Varying temperatures create different shapes. The snowflakes can create columns and even end up forming narrow needles. However, the most common shape is the flat hexagonal plate. This particular shape or rather the snowflake defining shape is a result of the molecular structure of water.

The water molecules possess a bent geometry and a polar design. Why? The hydrogens are negative, and the oxygen is somewhat positive. But stop, how does this result in the creation of a level snowflake? Now, we wouldn’t be telling you all of that here, would we? We would very much rather that you check out the amazing video by SciShow and learn the answers for yourselves.

What we can tell you is that the illustration is quite detailed and you won’t have any problem in keeping with the process that is being taught. The video’s description reads, ‘We’re told that all snowflakes are unique. But when you really think about them, snowflakes get even more interesting – as ice crystals forming in 3D space, why are snowflakes basically 2D?’
