Question

ice floats on water because ice is less dense than water. how is this helpful to fish that live in a lake?

Answer 1

Answer:

Since water ice floats, it helps life survive on Earth. In the winter, when surface temperatures are low enough for water to freeze, floating ice forms a layer of insulation on top of lakes and seas. This ice layer insulates the water below it, allowing it to stay liquid, which allows the life within it to survive.

Answer 2

Answer:

The whole river won't freeze due to the ice is floating. so fish are saved.
