Concept:A soil profile shows the vertical arrangement of soil layers from the surface to the bedrock.
Studying it helps farmers judge the soil's capacity to support different crops.
Explanation:The soil profile consists of distinct horizons, such as topsoil, subsoil, and parent material.
These horizons reveal the soil's depth, texture, organic matter content, drainage, and mineral availability.
From this information, a farmer can identify which crops are suited to the soil's properties.
Therefore, the soil profile is agriculturally important because it guides crop selection.
Option A, soil catena, refers to a sequence of soils across a landscape, not the profile's agricultural use.
Option B, land tenure, relates to land ownership and is not determined by soil layers.
Option D, weathering of rocks, is a geological process and is not a direct reason for studying the soil profile.
Answer:C. Gives indication of types of crops to grow
