Harmful Effects of Atmospheric Air on the External Environment

Mineral substances make up the solid part of the soil. In natural deposition, solid particles occupy a certain part of the mass of the soil, and the rest is made up of pits (porosity), which have different sizes and shapes in the range of particles and their aggregates. The total sum of these spaces is called soil porosity. Soil porosity is Capillary and non-capillary. Small particles of capillary porous soil are equal to the volume in the capillary range, and non-capillary porosity is equal to the volume of large pits between the elements of the macrostructure.
