Snowflakes Paper Designs

Snow (from Arabic ثلج) is water that falls from a cloud that has been frozen to solid and like rain. The snow consists of water vapor particles which then cool down in the upper air (see atmosphere, biosphere, climate, meteorology, weather) falling to the earth as soft, white, and soft crystalline snowflakes, ice-like frescoes, clusters of all).

At a certain temperature (called freezing point, 0 ° Celsius, 32 ° Fahrenheit), ordinary snow melts and disappears. The process as snow / ice changes directly into water vapor without melting is first called sublime. The opposite process is called deposition.

When the snow froze, it often becomes a small fragment called "snowflake". Snow is a prerequisite for winter sports such as skiing and sledding).
