The cross-section of a segment of soil showing the horizons or layers is known as the soil
Answer Details
The correct answer is "profile". A soil profile is a vertical section of the soil, from the surface down to the parent material, that displays a sequence of soil layers or horizons. These layers are differentiated from each other by their physical, chemical, and biological properties, and are used to study and classify soils. A soil profile is an important tool for understanding soil characteristics, such as soil structure, texture, depth, and fertility, and for identifying soil management practices that can be used to improve soil health and productivity.
