Question

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

Answer 1

Ice wouldn't float. Thus the bottom of the oceans would be ice. And the bottom of the ocean (if you believe in evolution) is where life began.

Thermophiles is the correct term to call them. Basically an organism that relies on heat instead of sunlight to generate energy. They are bad little creatures that live by sulfuric vents at the bottom of the ocean. It's crazy how they can even survive there.

So in summary, if life wasn't able to have ever began down there, life wouldn't be here today.

Answer 6

@cowgirlcrazy : I think there's been a misunderstanding here - ice floats on liquid water, as ice (at 0 deg C) has a lower density than liquid water (at 4 deg C). So the layer of ice on the water surface insulates the water at the bottom and prevents excessive heat loss from the water, allowing marine organisms to survive. If ice were denser than water, the ice would sink, allowing the water to freeze completely and prevent marine organisms from surviving in conditions of extreme cold.

Answer 7

@cowgirlcrazy66 : But your hypothesis on thermophiles being the originator of life isn't quite incorrect either.

Answer 8

I agree with @shiraz14
