Question

wRite the importance of anomalous explain of water​

Answer 1

Explanation:

At about 4°C water reaches its maximum density. This anomalous behaviour is an important characteristic of water, which played a significant role in sustaining marine life. Because of this unusual property, freezing of a body of water, due to changes in weather, begins at the surface.

Answer 2

The anomalous expansion of water helps preserve aquatic life during very cold weather. When temperature falls, the top layer of water in a pond contracts, becomes denser and sinks to the bottom. A circulation is thus set up until the entire water in the pond reaches its maximum density at 4°C. If the temperature falls further, the top layer expands and remains on the top till it freezes. Thus even though the upper layer are frozen the water near the bottom is at 4°C and the fishes etc. can survive in it easily.

I hope it helps you bestie!
