Although the shape of each snowflake is different, they all have two identical qualities: symmetrical graphics, and branches. When the water molecule is self-arranged into a solid snow or ice, the snowflake reflects the inherent order of water molecules. When the water molecule begins to condense, a weak hydrogen bond is formed between each other. The formation of snowflakes (and all substances transformed into solid state) are called crystallization. The molecules are arranged in the lowest energy state, which makes the attraction between them and the smallest. In the water ice on the earth, each molecule is connected to the other four molecules to form a lattice structure. Thus, the water molecules will move to have been designated. The most basic shape is a hexagon column, and the top end and the bottom end are hexagonal, and the six sides are triangles.
This arrangement is very similar to the ground brick: once the style is set, and put the first floor brick, all other floor tiles must be placed in a decided location to maintain the style. Water molecules are self-placed in accordance with low energy positions, they will fill in vacancies and maintain a symmetry; the "arm" of the snow is formed in this way. There are many kinds of snowflakes. The reason for these differences is that the snowflakes are generated in the atmosphere, and the atmospheric conditions are more complex. A snowflake crystal may be generated in some way, and then relatively varied due to changes in temperature and humidity. The basic hexagonal symmetry is still retained, but ice crystals will be branched in the new direction.
Due to the basic hexagonal column, the different styles of snowflakes are different because of the image of the branch, but it is basically the same. The branching of snowflakes is caused by different sides of the basic hexagonal column. Different sides are different in the atmosphere, the smooth cutting surface is slow, but not smooth, the outstanding cuts are expanded quickly. This situation is called "branch imbalance" - the faster the elongate cut surface, the faster, become branched ~~ This is the water molecule compared to the water molecules in the air, compare molecules The distance from the outstanding portion (branch) is close to the center plane, requires the lowest energy, allowing the water molecules to be crystallized in the fastest and lowest energy ~~ compared to the basic hexagon column of snowflakes The corner of the side is the least smooth cut, so the fastest (branch) is the fastest; it has created a wide variety of snowflakes.
Snowflake growth process
Different temperature humidity will create different snowflakes
A rare 12 petals and 3 petals of snowflakes are not common, but the basic principles of formation, and normal snowflakes are different.
