This is called anomalous expansion or the anomaly of water. It means that when water freezes, its solid form (ice) is less dense than its liquid form, which is why ice cubes float in water.
No everything is layered in density, water is much more dense than air. The whole planet is organized based on density with the core being the most dense and the exosphere being the least dense.
Not always - the density of a liquid may be greater or less than that of the solid form depending on the molecular structure and arrangement. For example, water is an exception as its solid form (ice) is less dense than its liquid form.
This tendency is called buoyancy. It is a result of the fact that the weight of the displaced fluid is greater than the weight of the object itself, causing it to float.

Air, oil, ice. One of the few substances that its solid form is less dense
Yes, liquid water is less dense than ice. When water freezes, its molecules form a crystalline structure that spaces them out, causing ice to be less dense than liquid water. This is why ice floats on water.
Ice floats on sea water because it is less dense than water. When water freezes, it forms a crystalline structure that spaces the water molecules farther apart, causing ice to be less dense than liquid water. This density difference allows ice to float on top of the denser sea water.
This is called anomalous expansion or the anomaly of water. It means that when water freezes, its solid form (ice) is less dense than its liquid form, which is why ice cubes float in water.
The structure of frozen water (ice) is less dense than the random arrangement of the water molecules in liquid water, thus ice floats because water becomes less dense when it is frozen. Because of buoyancy forces, an object placed in a liquid will float if it is less dense than the liquid and sink if it is more dense.

Ice is less dense than water
Ice is less dense than water at the same pressure. That is why ice cubes and icebergs float on the water.
The fact that ice floats on water is evidence that its solid form is less dense than its liquid form at its freezing/melting point. This is due to the unique arrangement of water molecules in the solid state, where hydrogen bonds create a lattice structure that causes ice to be less dense.
Technically it's neither true nor false without additional information (we would need to know the temperature and pressure). However, for "ordinary" conditions that you might find on or near the surface of the Earth, ice (solid water) is less dense than water (liquid water).
