Aggregation is dependent on the soil colloids and the cations associated with them. The view is advanced and some experimental support of it is described, that clay, as an “emulsoid,” protects the larger particles which by themselves are “suspensoid.” The soil aggregates are conceived as having large nuclei surrounded by particles which become smaller from the centre of the aggregate outwards, the clay ultimately imposing its “emulsoid” nature on the whole aggregate, and on the whole soil in normal cases.

That can happen spontaneously or due to the presence of flocculating agents. 2, Part 3, 244.CrossRefGoogle Scholar, Page 425 note 3 Zeitsch. In flocculation, particles don't just rise, they join together in a way that slows down the rise of other particles.
