The Answer is in the image, click to view ...

	No two snowflakes are the same because of the ice shape, sometimes it is a hexagonal, sometimes it is a tetrahedron.
	Some snowflakes are made of water, others are made of different molecules.
	They are not unique.
	On the molecular level they are unique. The way these atoms are found in a snowflake will be random and one small ice crystal could contain over a quintillion (1,000,000,000,000,000,000) water molecules.

	The hydrogen bonds contract so that they achieve the smallest distance from each other, and this results in tetrahedral liquid water.
	The hydrogen bonds are stronger than ever creating the least amount of surface tension and allowing for molecules to evaporate.
	The hydrogen bonds expand so that they achieve the greatest distance from each other, and this results in hexagonal ice crystals. It also results in spaces in between the ice molecules, which is what makes the solid phase of water less dense than the liquid phase.
	The oxygens separate from the hydrogens creating a point where the water will boil and break its molecule.

	9.167g/cm³

	If it sank in the water, many aquatic species would die as well as many animals, like polar bears who fish on top of floating ice.
	Very cold water is need for organisms to survive and the ice maintains colder than freezing temperatures under it.
	Ice floats on top of liquid water, insulating the water beneath it and allowing life to flourish underneath.
	It is the only way that you can get ice to sink into the ocean, if it were more dense, this could never happen and we would have frozen land.
	The lower density allows for stronger plants and animals, it provides them with the nutrients that they need.
