Question

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

Answer 1

Answer:

$\huge \tt \blue{ANSWER}$

️‍️

The anomalous behaviour 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.

Answer 2

Answer:

The anomalous behaviour of water is that it contracts from 0

0

C to

4

0

C and beyond 4

0

C it expands. Thus, the density of water

is maximum at 4

0

C. When the surrounding temperature falls,

the water in oceans and rivers cools down and say the temperature of

whole water reaches 4

0

C. Thus, the water reaches its maximum

density at this temperature. Below this temperature (4

0

C), the

water layer on the surface expands due to anomalous behaviour of water because of which it's density decreases. Thus, this colder layer remains on top and converts into ice which acts as an insulator and does not allow the temperature of water layer below it to fall below 4

0

C. In this way, a liveable temperature is maintained for the aquatic life under the oceans and rivers due to anomalous behaviour of water.
