Since the density of ice is less than the density of water, bodies of water freeze from the top to the bottom. This actually provides insulation to the water under the ice, preventing all the water from freezing. This allows life to continue under the ice, provided there is sufficient nutrients. If the density of ice was greater than the density of water, bodies of water would freeze from the bottom to the top, providing no insulation, and allowing all the water to freeze. This environment is not suitable for many life forms.

∙ 11y agoWater has high density at 4 degree centigrade. If ice were denser than water, it would have settled at bottom of sea and with this process going on entire sea water would have frozen causing death of all life forms in cold areas. Ice being poor conductor of heat only upper part get frozen and sea animals are safe in under water.

What is downwelling?
The Coriolis Effect causes water to be pushed onto shore and when the water on the surface of the sea becomes denser than the water beneath it, it sinks.
What makes an item to float or sink in water?
This depends on the density of this item: more denser than water-sink, less denser than water-float.

Would carbon float on water?
NO, because it is denser than water
Would a wood sink in water?
because it is denser than water
What is denser water or vinegar?
Vinegar is denser than water because vinegar is made of different substances that are denser than water, so that means vinegar is a little denser than water.
Is obsidian denser than water?
Yes. Obsidian is denser than water.

Why is wood denser than water?
Most types of wood are not denser than water--they float in/on water. For the wood types that are denser than water, the explanation is that they contain molecules that are denser than water (e.g. resin) and the average distance between molecules is smaller.
