A vertical section through the soil is referred to as soil

The correct answer is soil profile. A soil profile is a vertical section through the soil that shows its different layers, or horizons. Each horizon has unique characteristics, including color, texture, structure, and composition, that distinguish it from the other horizons. The soil profile provides a snapshot of the soil's history and development, including its formation and composition over time. It can also provide important information about the soil's fertility, drainage, and other physical and chemical properties. Understanding the soil profile is essential for effective soil management and conservation practices, as it helps to identify the best approaches for improving soil health and productivity.
