Question

Frozen water (ice) has less density than liquid water.

How does this property of water affect life on earth?

Answer 1

A: Ice floats on surface, sustaining life at the bottom of lakes and oceans.
B: Ice floats on the surface, helping animals migrate over lakes and bays.
C: Ice floats on the surface, maintaining sub-zero temperatures at the bottom of lakes and oceans

Answer 2

It means that water expands upon freezing, therefore it floats above water, allowing all aquatic life to be able to survive during cold temperatures or seasons
