Snow is actually frozen water, and as we know, ice has no color. Then the question arises as to why snow is white. Then reason is that each snow flake is made up of a large number of ice crystals. These crystals have many surfaces. And it is the reflection of light from all these surfaces that makes snow look white.

The crystals that make up a snowflake always arrange themselves in a special way. They either form six-pointed stars or thin plates shaped like a hexagon. Each branch of the six- pointed star is exactly like the others. While all the branches of snowflake are identical, no two flakes have ever been found to be exactly alike.
