Mountains are formed in the lithosphere. Litosphere is the solid shell of the planet Earth, which <span>includes the brittle upper portion of the mantle and the crust.
</span> It extends to a depth of about 60 mi (100 km) and is broken into about a dozen separate, rigid blocks, or plates .
Solids
The particles in solids are very close together. They are tightly packed, giving solids high densities.Liquids
The particles in liquids are close together. Although they are randomly arranged, they are still tightly packed, giving liquids high densities. The density of a substance as a liquid is usually only slightly less than its density as a solid. For example, the density of solid aluminium is 2.72 g/cm3 and the density of liquid aluminium is 2.38 g/cm3. This means that liquid aluminium floats on top of solid aluminium.Water is different from most substances: it is less dense as a solid than as a liquid, because its particles move apart slightly on freezing. This is why ice cubes and icebergs float on liquid water.Gases
The particles in gases are very far apart, so gases have a very low density.
