Soil cohesion

Soil cohesion refers to the internal forces that hold soil particles together, giving the soil a certain stability. These forces can arise from moisture bonds, mineral particles sticking together, or clay particles' electrostatic attraction. Cohesion helps soil resist deformation and prevents small masses from splattering apart under stress. It's a key factor in determining soil strength, stability, and behavior, especially in materials like clay. Understanding cohesion is important for construction, landscaping, and geotechnical engineering, as it influences how soil responds to loads and environmental conditions.
