Question

Frozen water (ice) has less density than liquid water.
How does this property of water affect life on earth?




Ice floats on the surface, sustaining life at the bottom of lakes and oceans.




Ice floats on the surface, helping animals migrate over lakes and bays.




Ice floats on the surface, maintaining sub–zero temperatures at the bottom of lakes and oceans.

Answer 1

Your answer is going have to be "Ice floats on the surface,sustaining life at the bottom of lakes and oceans"

Answer 2

Because in cold water there will be more oxygen when compared to warm water! and when ice floats it doesn't help in migrating animals and maintain sub zero temp that doesn't even make sense.
