Why do shallow lakes freeze quickly in winter, and deep lakes not at all?
To explain: The reason behind faster freezing of shallow lakes than deep lakes.
Answer to Problem 20A
The water in shallow lakes have water at edge which cools faster than deep lakes.
Explanation of Solution
Introduction:
Freezing: The transformation of liquid into solid at a temperature.
The amount of water in deep lakes are more than shallow lakes because of which the water is not uniform and freezing time increases. Due to this reason, shallow lakes freeze faster than deep lakes in winter.
Conclusion:
The water in shallow lakes have water at edge which cools faster than deep lakes.
