Question

How is aquatic life benefited by the fact that water has maximum density at 4°C?

Answer 1

•Water has maximum density at 4°C, below which it begins to expand.
•Hence, the density of water decreases below 4°C till 0°C .
•The layer of ice being less dense floats on water.
•Thus, the warm layer settles at the bottom in winters making it easy for the aquatic life to exist.
