A vertical section of soil through all its horizons is called a soil profile. It is a representation of the layers or horizons of soil from the surface downwards to the bedrock. The soil profile helps to provide information about the soil's properties, including its texture, structure, nutrient content, and depth, which is important for agricultural and environmental purposes. By examining the soil profile, scientists can understand the physical and chemical characteristics of different layers and how they interact to support plant growth and other ecological functions.
