A walk in a winter wonderland</ p>
The crunching sound of new snow following each step and the white snow-covered landscape is the dream of many people about a “white Christmas”. Snow is not only beautiful when viewed from afar, but also up close, each snowflake is equally beautiful up close.
Water is solid</p >
Snow is nothing strange but simply water in solid form when a drop of water sticks to a grain of dust or soot and freezes in the air in cold weather. For this to happen, the temperature in the air must be around -4 to -20 degrees Celsius.
Starting is a hexagon</p >
A snowflake begins as a flat piece with 6 sides just 0 1 mm in diameter. It has this shape due to the binding force between hydrogen molecules in water (H2O).
From crystal to sponge
When more water freezes into the hexagonal crystal than the flake The snow begins to have dendrites. Thanks to these dendrites, snowflakes have their characteristic star-like shape with infinite spikes depending on the temperature, wind conditions and humidity in the clouds they form.
Different forms of snow
It takes about 1 hour for a snowflake to fall from the clouds above to the ground. Temperatures below -5 degrees Celsius and higher humidity will produce larger snowflakes. In lower temperatures and drier conditions like those at the Earth’s poles, ice chips and lamellar crystals create snow.

Wetter and larger snowflakes are perfect for making snowmen, while colder snowflakes become drier powder snow that is often abundant on mountain slopes and is a favorable condition for making skiing.
“Last year’s snow”
Glaciers are formed by accumulating and solid snow again over time. Snow that melts and refreezes becomes a granular form of ice called firn. Actually the word “firn” is derived from a German word meaning “belonging to last year”. With blue or green light, sparkling glaciers have become important landmarks signaling climate change.

The white color of snow is in fact an optical illusion. Snow is made from water and the water has no color. But snow crystals are like mirrors; they reflect all light frequencies at the same time, so we see them as white with the naked eye.
Unique snowflakes
Regardless of their origin, snowflakes will always thrill us with their unique beauty and temporary nature because they will eventually melt again. flowing into water.
