why lakes and rivers do not freeze suddenly in winters

While water is moving, its temperature can drop under zero and it doesn't freeze. Clearly, speedier moving rivers are less inclined to freeze.
For lakes, the water's one of a kind thickness conduct shields them from freezing. Not at all like all substances, the strong type of water (ice) is less thick than the fluid shape. Ice cubes drift.
So when lakes freeze, the ice remains at the top. This protects the rest of the water from the colder air above. On the off chance that ice cubes sink, at that point lakes could freeze the distance to the base: the ice that formed would tumble to the base, constantly uncovering the top water to the cold air.
