When water freezes, bonds form between the water molecules and it turns into ice.Ice is less dense than water.This is because when it freezes the hydrogen bonds form an open lattice structure holding the water molecules in a fixed structure further apart than in the liquid state.As water is cooled below 4°C the density decreases.
Ice therefore floats on liquid water.Because ice floats, when water freezes the ice forms on the surface of the water insulating the liquid water below and allowing organisms to survive below the surface.
