parent material
A horizon is often darker than B horizon or C horizon because it is the topsoil and the topsoil might be covered with litter. The litter decompose and as you know become soil and it will be fresh soil. So the fresh soil is darker than B and C horizon
soil is in weathered parent rock
Gneiss is a high grade metamorphic rock, the product of various rock types being exposed to intense pressures and heat under the surface of the Earth. Orthogneiss is a gneiss whose parent rock was igneous, and paragneiss is a gneiss whose parent rock was sedimentary.
Mercury is mostly rock
Nothing, Chert has a parent rock and is made of mostly fossils and silica. It is not a parent rock. It has a parent rock.
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.
THe c horizon
parent material
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.
which horizon contains the least weathered parent material
c horizon is not subsoil it is parent material
It's a rock band. And they're called Bring Me the Horizon
A horizon is often darker than B horizon or C horizon because it is the topsoil and the topsoil might be covered with litter. The litter decompose and as you know become soil and it will be fresh soil. So the fresh soil is darker than B and C horizon
mostly o horizon, but some also occur in the a horizon
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.
