How is the snow formed?

Snow forms when small ice crystals stick to form snowflakes. Snow occurs when water vapors in the air freeze before they can trun into water. If they get big enough, they fall.

How the shape of a snowflake is like a star?

Water molecules that form ice crystals (snowflakes) are made from two hydrogen atoms bonded to one oxygen atom. The molecules in ince crystals join to one another in a hexagonal structure, to form together in the most efficient way. All snowflakes contain six or tweleve sides or points that form the shape.
