A soil survey should list the coefficient of linear extensibility (COLE) value. [2] Professional soil scientists can also analyze samples of a soil to determine its shrink-swell capacity. [2] Expansive soils will form large cracks, in roughly polygonal shapes, on the surface of the soil during dry periods. [3]

A mineralogical analysis is an X-ray diffraction (XRD) test that can identify specific clay minerals, such as montmorillonite, which would indicate shrink-swell qualities of the soil. [ 4 ] Field assessment for expansive soil may also be conducted, including a visual inspection to identify surface characteristics such as gilgai topography ...
Swelling index may refer to the following material parameters that quantify volume change: Crucible swelling index, also known as free swelling index, in coal assay; Swelling capacity, the amount of a liquid that can be absorbed by a polymer; Shrink–swell capacity in soil mechanics; Unload-reload constant (κ) in critical state soil mechanics
Soil sieve nests with dry soil aggregates after removal from a laboratory drying oven. Soil aggregate stability is a measure of the ability of soil aggregates—soil particles that bind together—to resist breaking apart when exposed to external forces such as water erosion and wind erosion, shrinking and swelling processes, and tillage.
Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.
The displacement of solids (sediment, soil, rock and other particles) usually by the agents of currents such as wind, water, or ice by downward or down-slope movement in response to gravity or by living organisms (in the case of bioerosion). erratic A piece of rock that deviates from the size and type of rock native to the area in which it rests.
