Except at EXTREME pressures (like over 200 MPa), ice is less dense than liquid water. In the case of polar water this is even more the case since polar water has a fair amount of salt dissolved into it, raising it's density, while the ice is nearly pure water.
Ice has a lower density than water.
The density of oil is what makes it float on water. Oil is less dense than water and does not mix or dissolve within the water. Therefore, it floats.The density of oil is what makes it float on water. Oil is less dense than water and does not mix or dissolve within the water.
if it sinks its more dense if it floats its less dense
Dense
The tendency of a less dense substance to float in a more dense liquid is called buoyancy. Acids are substances that form hydronium ions when dissolved in water.
In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.

Water is polar and oil is nonpolar. This is why they separate upon standing. The reason that the oil sits on top of the water is that it is less dense than water..
1. H2O is polar 2. Universal solvent 3. Solid form of water is less dense (ice)

Icebergs are already melting, but they only add very slightly to sea level rise (Icebergs are fresh water, which is slightly less dense than sea water).

Ice is less dense than water
Oil is less dense than water, and it also does not dissolve in water (the technical reason being that water is a polar solvent and oil is non-polar). Hence, oil floats on water.
