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

Answers

I think that Ice is denser than water to regulates the life of an organism living in the ice that would capable of them in living there. There are called Thermophiles that lives in by the sulfuric vents at the bottom of the oceans and if ice would be at the bottom, they would survive their.

Answer:

Water has various properties as frozen ice is less dense as 0.9340 g/cm cube compared to density of water at room temperature is 997 kg/m cube.

Explanation:

The dissolving effect of water is fundamental to life from son earth and it's due to this property of water that makes it more mobile and more elastic. As wherever water goes it carries with it the dissolved salts, nutrients and other chemicals that support life.

If water is at room temperature it can be used with other substances as to from compounds and give the desired results upon reacting with the various elements. As most liquids contract when they are cooled to ice forms that we have seen in glaciers the ice caps and polar landmasses have life frozen in freshwaters.

Ice can carry along with it various types of gases and rare earth that can be remained preserved inside the earth for years. Even earth core consists of liquid water which is itself a sign that life on earth is a result of the changing forms of water sphere on earth.
