Answer to Question 1

As soils age they may develop horizon positions and properties that are between master horizons. Such
transitional layers are identified by two master letters with the dominant one written first. An AB layer
lies between the A and B horizons but is most like the A horizon. Layers can be further identified by a
lowercase letter suffix denoting a trait of the layer (Ap). Numbers can be used to indicate further
subdivisions (Bt1).
