Grasping the relationships between soil’s different phases is vital in geotechnical engineering and soil science. These phases—solid particles, water, and air—interact in ways that deeply influence key soil properties, such as density, porosity, and moisture content. The balance and interaction of these phases dictate how soil will perform under various conditions. By studying these relationships, engineers can more precisely predict soil behavior, which is critical for designing and building stable, safe structures.
