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.

Is cold water denser than room tempurture water?
yeah cold water is denser than room temperature (warm) water.
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.
Why oil is more denser than juice?
Juice is much denser than oil. Juice will sink and some what combine with water while oil floats on top of water.
What Oil floats on water because it is denser true or false?
Oil floats on water because water is denser than oil.
Why is ocean water denser than freshwater or pure water?
The water of the oceans is denser because of the high level of salt it contains.
Would a wood sink in water?
because it is denser than water
Would carbon float on water?
NO, because it is denser than water
What the density of water is equal to 1.0 gcm3. A substance with density equal to 2.1 gcm3 would in water?
The substance with a density of 2.1 g/cm3 will sink in water, as it is denser than water (density of 1.0 g/cm3). This means that the substance will not float but will sink to the bottom of the container filled with 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?

chicken
What is denser fresh or sea water?
Salt water is denser than fresh water.
Is charcoal denser than water?
Yes, charcoal is denser than water. Charcoal has a higher density than water, which means that it will sink in water.
Is a marble denser than water?
Yes if it floats. Does Marble float in water? If not then the answer is no.
What is the movement of water that occurs when a mass of water is denser than the surrounding water?
Denser water sinks.
What would sink in water?
Objects that are denser than water or have spaces that allow water to fill in quickly would sink in water. Materials like lead, iron, and rocks are denser than water and will sink. Objects like wood or plastic may float depending on their density.
