Soil Cohesion is the component of shear strength of a rock or soil that is independent of interparticle friction. In soils , true cohesion is caused by following: Electrostatic forces in stiff overconsolidated clays (which may be lost through weathering) Typical soil cohesion values for different soils.

WebbGrain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks.The term may also be applied to other granular materials.This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain. A single grain can be composed of several crystals.
