Weathered rock fragments in the soil profile are the result of the breakdown of parent rock material due to physical, chemical, and biological processes. These fragments add to the mineral content of the soil and contribute to its overall composition and fertility. They play a role in providing stability to the soil structure and influencing its drainage and water holding capacity.
Solid rock is being weathered into soil in the parent material layer or C horizon of the soil profile. This is where the physical and chemical breakdown of the rock material occurs, leading to the formation of soil.
The bottom horizon in a soil profile that contains only partly weathered rock is called the C horizon. In this horizon, the rock is partially weathered and has started to break down into smaller particles, but has not fully transformed into soil yet.
The part of the soil profile that is made up of partly weathered rock is called the regolith. Regolith is the layer of loose, fragmented material that sits above the unaltered bedrock in the soil profile.
The part of a soil profile that is made up of partly weathered rock material is known as the regolith. This layer typically consists of broken rock fragments mixed with soil particles and is an important component in soil formation.
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.

C horizon beacuse that part of the soil profile is made out of rock and so how can you do weathering without rock?

The process of solid rock being weathered into soil typically occurs in the parent material layer of the soil profile, which is the layer closest to the unaltered bedrock. Weathering processes, whether physical or chemical, gradually break down the solid rock into smaller particles to form the soil.
In the C horizon
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.
Solid rock is being weathered into soil in the bedrock layer of the soil profile, which is located at the bottom below the subsoil and topsoil layers. Weathering processes such as physical (freeze-thaw cycles) and chemical (acid rain) weathering act on the solid rock over time, gradually breaking it down into smaller particles that mix with organic matter to form soil.
you are likely to find dark, humus-rich soil in an A-horizon profile because that's where dark soil is found & the composition is the particles of weathered rock materials mixed with humus.
