Chemical weathering.
Chemical weathering
Weathered rocks that are composed of smaller fragments and grains are referred to as sedimentary rocks. These rocks are formed through the process of erosion, transportation, deposition, and lithification of the weathered materials.
Soil, (regolith).
That forms sedimentary rock.
The rock that has no exposure to chemical or mechanical weathering is known as "unweathered rock" or "fresh rock." This type of rock is typically found deep underground or in areas shielded from environmental influences. It retains its original mineral composition and structure, making it distinct from weathered rock, which has undergone changes due to external processes.
Chemical weathering
Weathering materials that have been altered in terms of their characteristics and chemical composition have undergone weathering processes. This could involve physical breakdown, chemical decomposition, or biological alteration due to exposure to various environmental factors. The end result is a transformation of the original material into a different form, often leading to the formation of new minerals and substances.
Weathered orthoclase clay is a type of clay that has undergone physical and chemical weathering processes over time. These processes break down the orthoclase mineral in the clay, altering its composition and texture. Weathered orthoclase clay is often softer, more porous, and may have a different color compared to fresh orthoclase clay.

The term for rock that has been weathered to become soil is "parent material." Parent material refers to the original rock or mineral material that has undergone weathering and other natural processes to form soil.
Weathered rocks that are composed of smaller fragments and grains are referred to as sedimentary rocks. These rocks are formed through the process of erosion, transportation, deposition, and lithification of the weathered materials.
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.
Erosion
Soil, (regolith).
of Weather, Made sloping, so as to throw off water; as, a weathered cornice or window sill., Having the surface altered in color, texture, or composition, or the edges rounded off by exposure to the elements.
That forms sedimentary rock.
Deposited weathered rocks can form sedimentary rocks through processes like compaction and cementation. These rocks are made up of fragments of pre-existing rocks that have undergone weathering and erosion before ultimately being deposited and lithified to form a new rock.
