1.Snow does not start out as what we see fall from the sky. In fact, it is in fact precipitation of ice in a flake or cluster form. The term snow is often used for both the white materials falling out of the sky and that on the ground.
2.However these two forms are completely different. When falling from the sky, it is in the form of crystalline ice. Ice crystallizes in six-sided objects. This can be seen under magnification.
3.After reaching the ground, snow loses it's crystalline shape and becomes granular. Therefore, falling snow and snow on the ground should be considered two different objects because of how they differ.
4.1.Formation of Snow-
4.2.Snow crystals are crystals of ice formed within the atmosphere at temperatures below freezing.
4.3.-
This forms due to condensation of water vapor on a very small ice crystal or dust particle. This condensation does not hit a liquid state, it goes directly fr om water vapor to ice. This is known as sublimation.
4.4.-
Water droplets can exist at temperatures as low as -40 degrees Fahrenheit. When these droplets come in contact with tiny ice crystals, they began evaporating and freeze onto the crystals nuclei. The formation of these hexagonal structures of ice takes place in uniformity. If an excess of moisture is present in the atmosphere, the crystals change into snow crystals.
4.5.-
Typical Snow crystals are see through like glass and are typically from .02 to .5 i nches in diameter. They can be examined best if gathered by a black cloth when the air temperature is at or below freezing.

Put simply, when it gets cold enough (generally -1 to 3 degrees Celsius) what would have been rain becomes snow. It can be too cold to snow. Generally in very cold places where it snows a lot, you'll notice it's slightly warmer on the days it snows. Snow clouds tend to have a greenish tinge to them, so if you're a skier you can see them coming and get excited!!

Snow is precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes. Since it is composed of small rough particles it is a granular material. It has an open and therefore soft structure, unless packed by external pressure.
Snow is commonly formed when water vapor undergoes deposition high in the atmosphere at a temperature of less than 0°C, and then falls to the ground. Snow is less dense than rain, which means the same amount of moisture will produce a greater volume of snow than it will rain. One rule of thumb is that the water in ten units of snow is equivalent to one unit of rain.

Water evaporates from the ocean and lakes. It rises with the warm are and it condenses to form the white clouds. When the temperatures lower it hits a dew point and can form big enough droplets to fall out of the sky. If it's also below freezing, when the droplets fall they freeze & crystalize. Result : snowflakes.

Through precipitation. When the temperature above 0 degree celcius is rain, below 0 degree is snow. In minus degree the weather frozen water into solid form, so water turns into snow because weather is freezing cold.

When it gets cold enough, the water in the atmosphere freezes into tiny ice crystals that can fall all the way to the ground if the temperature never gets too warm along the way.

snow comes from the same place as rain...the clouds, which get it from the air, which is saturated by water evaporating from lakes, oceans, rivers, ponds, etc. the only difference is that snow freezes as it falls towards the ground.
