Frozen water is less denser than liquid water so that's why ice floats on the water in cold areas.

Ice is less dense than liquid water because when the water becomes solid due to low temperature, the density of ice become decreases. Due to less density, the ice floats on the water surface.

Water is attracted due to its polar nature so adhesive forces pull the water toward other molecules. Water is transported in plants through both cohesive and adhesive forces. These forces pull water and the dissolved minerals from the roots to the upper parts of the plant.

So we can conclude that frozen water is less denser than liquid water so that's why ice floats on the water in cold areas.
