A soil horizon is a distinct layer in the soil that is parallel to the soil surface and has unique characteristics. A soil profile is a vertical section of the soil that shows the arrangement of these horizons from the surface to the underlying bedrock. Soil horizons collectively make up the soil profile, providing information about the soil's properties and history.
The three distinct soil horizons in a mature soil profile are: the topsoil (A horizon), the subsoil (B horizon), and the parent material (C horizon). Each horizon has unique characteristics and composition that contribute to the overall soil profile.
Partially weathered parent material is found in the C horizon of a soil profile.
The uppermost layer in a well-developed soil profile is the O horizon, also known as the organic horizon. This layer consists of organic matter such as decaying leaves and plant material. It is typically found at the surface of the soil profile.
A Hutton soil profile is a type of soil profile that typically consists of three main horizons: A horizon (topsoil), B horizon (subsoil), and C horizon (parent material). These profiles are common in areas with moderate to high rainfall and have well-developed soil layers. They are named after the scientist R. J. Hutton who studied soil formation processes.
The uppermost layer in a well-developed soil profile is the O horizon, also known as the organic horizon. This layer consists of organic matter such as decomposing plant material and leaf litter. It is typically found at the surface of the soil profile.
Partially weathered parent material is found in the C horizon of a soil profile.

the A Horizon
The uppermost layer in a well-developed soil profile is the O horizon, also known as the organic horizon. This layer consists of organic matter such as decaying leaves and plant material. It is typically found at the surface of the soil profile.
B-horizon
A Hutton soil profile is a type of soil profile that typically consists of three main horizons: A horizon (topsoil), B horizon (subsoil), and C horizon (parent material). These profiles are common in areas with moderate to high rainfall and have well-developed soil layers. They are named after the scientist R. J. Hutton who studied soil formation processes.
The uppermost layer in a well-developed soil profile is the O horizon, also known as the organic horizon. This layer consists of organic matter such as decomposing plant material and leaf litter. It is typically found at the surface of the soil profile.
The parent material is usually found in the C horizon of a soil profile. This horizon is located below the A and B horizons and consists of partially weathered rock or unconsolidated material from which the soil has developed.
The 5 layers in a complete soil profile are the O horizon (organic matter), A horizon (topsoil), E horizon (eluviated layer), B horizon (subsoil), and C horizon (parent material). These layers collectively make up the soil profile, each with different characteristics and roles in supporting plant growth and ecosystem function.
