Chemical weathering
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.
Two characteristics that affect the rate of weathering are the type of rock or material being weathered, such as its composition and structure, and the climate in which the weathering occurs, including temperature, precipitation, and humidity levels. These factors can influence the speed at which physical or chemical processes break down rocks and minerals.
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.
Partially weathered parent material is found in the C horizon of a soil profile.
Chemical weathering
Chemical weathering. This process involves the alteration of the minerals and chemical composition of rocks or materials due to exposure to environmental factors like water, oxygen, and biological agents. Over time, this results in the breakdown and transformation of the rock into different components.

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.
False. The type of rock being weathered significantly influences the characteristics of the soil formed. Different rocks contain varying minerals, which affect soil composition, nutrient availability, and drainage properties. Therefore, the weathering of specific rock types directly impacts the soil's physical and chemical properties.

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.
Soil, (regolith).
Erosion
That forms sedimentary rock.
