Top·soil - the upper fertile layer of soil from which plant roots take nutrients.
Hu·mus - a brown or black complex variable material resulting
from partial decomposition of plant or animal matter and forming
the organic portion of soil.
Eluviation - the transportation of dissolved or suspended material within
the soil by the movement of water when rainfall exceeds evaporation.
Regolith - the layer of loose rock particles that covers the bedrock of most land
on earth.
Bedrock - the solid rock beneath loose rock particles or soil.
Mineral - a solid homogeneous crystalline chemical element or compound
that results from the inorganic processes of nature; broadly : any of various
naturally occurring homogeneous substances (as stone, coal, salt, sulfur,
sand, petroleum, water, or natural gas) obtained usually from the ground.
Here is a small diagram to help you and i will describe each part briefly.
0 Horizon (Humus)
The top, mostly organic layer of soil, made up of leaf and humus (decomposed organic matter).
A horizon (topsoil)
This is where seeds germinate and plant roots grow. It is made up of humus (See above) mixed with minerals.
E horizon (eluviation layer)
This eluviation layer is light in color; It is made up of sand and silt, It has lost, however, most of its minerals and clay because of water dripping through soil (Process of eluviation)
B horizon (Subsoil)
Also called the subsoil, this contains clay and minerals such as calcium and iron. These get received from the layers above.
C horizon (regolith)
Also called regolith: It has slightly broken-up bedrock (From the layer below) And plant roots find it impossible to get into this layer, in fact, very little organic material is found in this layer at all!
R Horizon (Bedrock)
This is the untouched rock that lays dormant under all of the other busy soil layers. Another word for this layer is bedrock. Not much to say about thus as not much is happening.
yes, soil have diffrent types of layers in it...................
3 layers of different kinds of soil is you count humus,5, (humus, topsoil, midsoil, poor soil, bedrock, you can call it 3 though, humus isn't actual soil its dacayed plants and animals)
Soil LayersThe layers of soil are:Top SoilSub SoilParent Materialbedrock
the different sections have different materials
soil layers are called horizons
Permeability is the rate (speed) that rainwater seeps through the different layers of soil.
soil is the earth and it supports us in staing alive.

When soil is cut vertically different layers are seen called horizons which are named A ,B ,C etc.

The horizon is the vertical sequence of the layers of soil.
sun light bends
A vertical sequence of distinct soil layers is a soil profile!
Those soil layers are permeable.
