6 Fun facts about snowflakes (2024)

FAQs

What percentage of snowflakes are 6 sided? ›

Empirical studies suggest less than 0.1% of snowflakes exhibit the ideal six-fold symmetric shape. Very occasionally twelve branched snowflakes are observed; they maintain the six-fold symmetry.

They were born from 1981-1996 so now roughly aged between 22-37 and due to a surge in birth rates in the 80s and 90s, there's a lot of them. They currently make up around half of today's workforce and that's set to rise to a staggering 75% by 2025.

Those six points happen because every snowflake is made up of billions and billions of water molecules, White said, and at the very core, are six water molecules essentially "holding hands" to make a hexagon shape.

The researchers took fresh snow samples at 19 locations around the globe, including Antarctica, and found DNA-containing cells in all of them.

When water becomes warm, it evaporates as water vapour into the air, forming clouds. When it cools again above our heads the vapour turns back to water and rain falls back down to the ground. When it's really cold, the water vapour freezes into crystals, causing snow.

In a typical winter storm, snowflakes begin their descent from a cloud layer about ten thousand feet aloft. Assuming an average fall speed of 3.5 feet per second, a snowflake would take more than 45 minutes to reach the ground.

Snow crystals are sensitive to temperature and will change in shape and design as they fall from the cloud and are exposed to fluctuating temperatures. To have two snow crystals or flakes with the same history of development is virtually impossible. High-resolution images show snowflake complexity.

A bit of snowflake watching may turn up some 12-sided snowflakes, as these occur along with the normal 6-sided variety. They're not real common, but you can spot them if you look. Some snowfalls bring quite a few twelve-siders, although no one really knows what weather conditions are best for making them.

Snowflakes May Have Different Designs, But They Always Have Six Sides.

Many people assume you need a microscope or expensive photographic equipment to see the shapes of snow crystals. In fact, you can very often see a lot of detail with the naked eye – just look carefully as they fall on your gloves or coat and you'll be surprised.

Is snowflake a crystal? ›

A: A snowflake begins to form when an extremely cold water droplet freezes onto a pollen or dust particle in the sky. This creates an ice crystal. As the ice crystal falls to the ground, water vapor freezes onto the primary crystal, building new crystals – the six arms of the snowflake.

Plates sometimes grow as truncated triangles when the temperature is near -2 C (28 F). If the corners of the plates sprout arms, the result is an odd version of a stellar plate crystal. These crystals are relatively rare. Surprisingly, no one knows why snow crystals grow into these three-fold symmetrical shapes.

Each snowflake is made of as many as 200 ice crystals. Some snowflakes are symmetrical, like the type that you cut from paper. They form a hexagonal (six-sided) shape because that is how water molecules organize themselves as they freeze. Some snowflakes become lopsided if they fall sideways to the ground.

This system defines the seven principal snow crystal types as plates, stellar crystals, columns, needles, spatial dendrites, capped columns, and irregular forms. To these are added three additional types of frozen precipitation: graupel, ice pellets, and hail.

Each snowflake falls and floats through clouds with different temperatures and moisture levels. This shapes each snowflake differently. Two snowflakes from the same cloud will have different sizes and shapes because of their different journeys to the ground.
