Anomalous Behaviour of Water
Water shows some exceptional behaviour that is when it is heated at 0°C, it contracts instead of expandingand it happens till it reaches 4 °C. The volume of a given amount of water is minimumat 4 °C therefore its density is maximum(Refer the Fig). After 4 °C water starts expanding. Below 4 °C, the volume increases, and therefore the density decreases. This means water has maximum density at 4 °C.
Advantages of Anomalous behaviour of Water
Because of this property of water in lakes and ponds freeze only at the top layer and at the bottom it does not, butif the water freezes at the bottom also then animal and plant life would not be possible.
The information we get from the above graph means that the density increases as its temperature rises from 0°C to 4 °C and density decreases after 4°C.

The water in the central part of the Hope's vessel cools towards 4 °C (39 °F) (and thus becomes denser) it sinks to the bottom of the vessel, displacing the warmer water. At this temperature the anomalous expansion of water occurs . Cooling towards 0 °C (32 °F) will cause the now less dense water to rise.
