The anomalous behavior of water refers to the expansion of water when it freezes instead of contracting.

the anomalous expansion of water is where water contracts from 0to 4 degrees and then expands.In winters when the large water bodies turn deadly cold,the anomalous expansion of water helps in freezing only the top layer of the water bodies so that the marine life can survive underneath.This is how the anomalous expansion of water is useful in conservation of bio diversity

The expansion of water when it is cooled from four degree centigrade to zero degree centigrade is known as "anomalous expansion of water."

The unusual behaviour of water, when it expands below

4° celsius to

0° is called anmalus expansion of water.

water has the property of expanding when cooled at a temperature below 4`C.

As a result water pipes burst due to the anomalous (strange) expansion of water in the colder regions.

Anomalous expansion of water and bursting of water pipes during winter is because ice takes more space than water
