water exhibits an anomalous behaviour
it contracts on heating between 0 degree Celsius and 4 degree celcius.
volume of a given amount of water decreases as it is cooled from room temp until it's temp reaches 4 degree celcius.
below 4 degree celcius volume increases.. THE ABOVE DIAGRAM ILLUSTRATES THERMAL EXPANSION OF WATER

In cold regions, in winter, the rocks crack due to anomalous expansion of water because when the water starts to expand when the temperature drops to low.
Explanation:
- The volume of water 'decreases' as it is cooled from 'room temperature' until it reaches 4-degree Celcius.
- There is no space for the water to expand inside the rocks which exerts high pressure inside them and they start breaking.
- It is also a fact that below 4 degrees, the volume of the water starts increasing and the water particles inside a rock do not have much space to move around which cause them to be 'broken down'.
