Detailed answer to the quiz question
Most snow crystals have a hexagonal shape. This is due to the molecular structure of water and the way in which water molecules freeze. When water becomes ice, the molecules arrange themselves in a hexagonal (hexagonal) crystal structure based on the atomic arrangement of oxygen and hydrogen atoms. This hexagonal symmetry is the basic pattern that gives snow crystals their typical shape.
Snow crystals form in clouds when water droplets cool below freezing point and small particles in the air freeze. The resulting ice crystals begin to attract water vapor, which is deposited on them and causes them to grow. The rate of growth varies in different directions of the crystal, resulting in the fascinating and complex patterns we can see with the naked eye. Even though each snow crystal is unique and differs in its details, the basic hexagonal structure always remains the same.
The outer branches of the snow crystals develop symmetrically because the conditions – such as temperature and humidity – are roughly the same around the entire crystal. The result is a complex, intricate pattern with six arms that often end in geometric shapes. The conditions under which the crystal grows influence its exact shape, so there is an infinite variety of snow crystals. However, the hexagonal structure remains the common basis, as it results from the physical properties of water.
