What are five ways in which the surface of Earth's crust can move

So basically we have to know does the material's characteristics/compositions affect its density?

Explanation: Density is defined as the ratio of the mass of a material to its volume at a specific temperature and pressure. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. The Density of material is changed by changing its mass to volume ratio or by changing its temperature or by changing its pressure, the density of material changes. From the above description, it can be inferred that a material's composition or chemical characteristics may remain unchanged if density changes by changing the pressure or temperature of the material.
