Colloids
Very small, finely divided solids (that do not dissolve) that remain dispersed in a liquid for a long time due to their small size and electrical charge.

Colloids: Fine-grained material in suspension. Specifically refers to a particle-size range of less than 0.00024 mm.
Colluvial Deposits: Weathered, unconsolidated materials transported and deposited by gravity.
Colloids Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.

A-Horizon - The uppermost zone in the Soil Profile, from which soluble Salts and Colloids are leached, and in which organic matter has accumulated. Generally this represents the most fertile soil layer and constitutes part of the Zone of Eluviation.
