Question

What is the role of anomalous behaviour of water in preserving aquatic life in regions of cold climate ​

Answer 1

Answer:

The anomalous behavior of water is that from 0°C to 4°C it contracts and beyond 4°C it expands.  This ice acts as an insulator and does not allow the temperature of the water layer below it to fall below 4°C. This ensures that a liveable temperature is maintained for aquatic life under the oceans and rivers.
