Answer Details
The C-horizon in a soil profile can be described as the zone relatively unaffected by soil-forming processes. This layer is located beneath the A and B horizons and is composed of partially weathered parent material. It is usually the deepest layer and lacks the characteristics of the upper layers, such as organic matter, humus, and nutrients, as it has not been subjected to the same degree of weathering and leaching. Therefore, the C-horizon is considered to be the layer with the least biological activity and is also referred to as the "parent material."
