MoreBulk density provides a second way of defining sediment weight. Bulk density is defined as the mass of a unit volume of dry sediment, including both solids and pores. Brady (1974) discussed the factors affecting bulk density, indicating that loose and porous materials have lower bulk densities than more compact materials. Sandy soils, particularly those with low organic matter, generally fit ...

MoreDensity is defined as the mass per volume. In rocks, it is a function of the densities of the individual grains, the porosity, and the fluid filling the pores. There are three types of density in rocks: dry density, wet density, and grain density. The data table lists the dry, wet, and grain densities of the samples.
