Geologist may determine the density of earth materials by measuring the mass of the object and its volume.
<h3>What is density ?</h3>
The mass of a substance per unit of volume is its density. Density is most frequently represented by the symbol, however Latin letter D may also be used. The formula for density is mass divided by volume
Earth's density is around 5.513 g/cm3 if you average the density throughout the entire globe. However, if you compare the density of the Earth by its layers, you'll notice that it rises continuously from the crust to the core.
