A horizon
Bedrock is not a layer of mature residual soil. Bedrock is the solid rock underneath the soil layers that make up the Earth's crust. Residual soil forms from the weathering of bedrock over time.
== == This layer is called bedrock.
The layer of solid rock under the soil is called bedrock. Bedrock is the hard, solid rock beneath the Earth's surface that forms the foundation for soil and other materials above it.
The three layers that form the soil profile are topsoil, subsoil, and bedrock. Topsoil is the uppermost layer rich in organic matter and nutrients, while subsoil is the middle layer with less organic material and more minerals. Bedrock is the solid rock layer found beneath the soil layers.
The layer of bedrock near Earth's surface that forms a continuous shell around the Earth is called the lithosphere. This layer includes the crust and upper part of the mantle and is divided into tectonic plates that move and interact with each other.

The layer of solid rock under the soil is called bedrock. Bedrock is the hard, solid rock beneath the Earth's surface that forms the foundation for soil and other materials above it.
The layer of solid rock found under the soil is called bedrock. Bedrock is composed of consolidated rock that forms the base of the Earth's crust and provides a strong foundation for the layers above it.
The three layers that form the soil profile are topsoil, subsoil, and bedrock. Topsoil is the uppermost layer rich in organic matter and nutrients, while subsoil is the middle layer with less organic material and more minerals. Bedrock is the solid rock layer found beneath the soil layers.
A soil profile is a vertical section of soil that ranges from the surface to the bedrock. Each layer of a soil profile is referred to as a soil horizon.Horizon O is the top layer, where organic material is presentHorizon A is top soilHorizon B is subsoilHorizon C contains weathered rock.
The layer of bedrock near Earth's surface that forms a continuous shell around the Earth is called the lithosphere. This layer includes the crust and upper part of the mantle and is divided into tectonic plates that move and interact with each other.
The section of the soil profile that lies directly above the bedrock is called the parent material. This layer is typically weathered bedrock or unconsolidated material from which the soil has developed over time. It plays a key role in determining the characteristics of the overlying soil horizons.
Solid rock is being weathered at the bedrock layer, which is the deepest layer of the soil profile. Weathering processes like physical breakage and chemical decomposition act on the bedrock to gradually break it down into smaller particles, contributing to soil formation.
A is the layer of the soil profile in which most organic material is found.Specifically, there are five layers in the soil profile. The first, A layer of organic matter claims the first two inches and contains plant debris. The second, A layer of surface soil comprises the next ten inches down. Below it will be found the third, B layer of subsoil containing aluminum, clay, iron and organic compounds and going down 30 inches; the fourth, C layer of parent rock going down 48 inches; and the fifth, final, R layer of bedrock.
The layer of bedrock near Earth's surface that forms a continuous shell is called the lithosphere. It consists of the crust and the upper part of the mantle, and it is divided into tectonic plates that float on the semi-fluid asthenosphere beneath.
