Soil morphology is the branch of soil science dedicated to the technical description of soil, [1] particularly physical properties including texture, color, structure, and consistence. Morphological evaluations of soil are typically performed in the field on a soil profile containing multiple horizons .
Soil morphology indicates that the first terrace of Valley A is missing in Valley B and the third terrace of Valley A is missing in Valley C. This simple example can be extended to valley-to-valley correlation of glacial sequences, colluvial deposits, eolian sands, marine terraces, and ancient lacustrine deposits.
Jul 29, 2015 · From a morphological stance, the Natural Resource Conservation Service (NRCS) defines soil as: “a natural body comprised of solids (minerals and organic matter), liquid, and gases that occurs on the land surface, occupies space, and is characterized by one or both of the following: horizons, or layers, that are distinguishable from the initial m...

Soil organisms are commonly divided into five arbitrary groups according to size, the smallest of which are the protists —including bacteria, actinomycetes, and algae. Next are the microfauna, which are less than 100 microns in length and generally feed upon other microorganisms.
