Temperature is a measure of heat and kinetic energy of molecules. So as you reduce the temperature of a substance, the molecules or atoms that make it up stop moving/vibrating and tend to stay more in one place and thus eventually solidify.
For water, the temperature at which this happens is 0 degrees Celsius. Of course, it's a little more complicated than this, but as a brief (and mostly correct) description, this works! :)

It is due to its freezing point.Molecular space in water goes to contract step by step and water changes to ice.Below odegree c the density of water is going to be low.

Because it freezes. The molecules have been cooled to the point that they are no longer in liquid form.

Because it freezes to ice at that temperature. (0 c)
