Conditions and Effects

The Conditions and Effects hierarchy contains descriptors for physical characteristics perceptible in or on materials, objects, or environment that are the result of particular physical circumstances or of spontaneous physical or chemical change. Relation to Other Hierarchies: Descriptors for processes of physical change are found in the Processes and Techniques hierarchy, and some of those descriptors can designate both the process and the effect (e.g., corrosion). Descriptors for forms or effects purposefully added to objects as ornament (e.g., air traps) are found in the Design Elements hierarchy.
