Snow

In clouds, water steam crystallising forms snowflakes. Also at a cold snap of pairs from air crystallises on trees and subjects, houses and designs forming a cover from hoarfrost.

Snowflakes falling from the sky have six-final crystal forms. It is connected with structure of molecules of water. Between beams of a crystal of water corners only in 60 and 120 degrees are possible.

Snow on the one hand protects soil from strong промерзания at which plants and their roots perish, and on the other hand at a fair weather reflects 90 percent of a sunlight and thermal beams in space. Therefore the snow cover detains warming up of soil from direct solar beams will not thaw yet in the spring.

For a long time it is noticed that in the winter in the north in cloudy weather is warmer, than in the clear. Clouds create effect of a blanket detaining both solar warmly and warmly radiated by the Earth.
