which horizon contains the least weathered parent material
Partially weathered parent material is found in the C horizon of a soil profile.
All these soil types have a surface layer or the A horizon. These soils also have subsoils or a Bt horizon, parent material that is A C horizon, and bedrock or the R horizon.
The A horizon in soil is typically made up of mineral and organic material. In some instances the A horizon is only 2 to 3 inches deep, although it can be much deeper if the land has been plowed.
C-horizon is made of weathered, large parent rock. It also contains other minerals and clay. It is the third layer under the B-zone.
1. O - Layers/horizon (organic layer, containing humus). 2. A - Layer/horizon (top soil). 3. E - Layer/horizon (zone of elluviation). 4. B - Layer/horizon (sub-soil). 5. C - Layer/horizon (zone of illuviation/accumulation). 6. D - Layer/horizon (parent materials/bed rocks).
The C horizon contains mainly parent material, while the B horizon contains mainly clay particles and the A horizon; mainly silt sized particles and humus
c horizon is not subsoil it is parent material
The O horizon contains the most organic matter. The O horizon overlies the A horizon which is known as the mineral horizon. O - organic A - mineral E - elluviation B - illuviation C - parent material R - bedrock This is the order in which you will see standard soil horizons.

Soil layers are called soil horizons. Typically, a soil includes an A horizon, a B horizon and a C horizon. In laymen's terms: A horizon = topsoil B horizon = subsoil C horizon = parent material (the stuff in which the soil formed)
