Density of Rocks and Soils
What we are actually comparing is the mass per unit volume, that is, the density. In order to determine these densities, we might weigh a cubic centimeter of each sample. If the rock sample weighed 2.71 g and the soil 1.20 g, we could describe the density of the rock as 2.71 g cm –3 and that of the soil as 1.20 g cm –3.

Introduction. Unlike other physical properties, the densities of the commonest rock forming minerals are remarkably close together. The actual densities of pure, dry, geologic materials vary from 880 kg/m 3 for ice (and almost 0 kg/m 3 for air) to over 8000 kg/m 3 for some rare minerals. Rocks are generally between 1600 kg/m 3 (sediments) and 3500 …
