Question

Advantages of anamalous expansion of water

Answer 1

Answer:

Explanation:

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.

Answer 2

Answer:

The anomalous expansion of water may lead to flood or tsunami because if the water level suddenly increase it will lead to destruction
