13.3 Stream Erosion and Deposition – Physical Geology

On the other hand, a 0.01 mm silt particle only needs a velocity of 0.1 cm/s to remain in suspension, but requires 60 cm/s to be eroded. In other words, a tiny silt grain requires a greater velocity to be eroded than a grain of sand that is 100 times larger! For clay-sized particles, the discrepancy is even greater.

Grain size - Wikipedia

Grain 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. ...
