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.
The soil is typically composed of different layers known as horizons. The main layers are topsoil (rich in organic matter and nutrients), subsoil (less organic matter, more minerals), and bedrock (the solid rock layer). Each layer has distinct characteristics and plays a role in supporting plant growth.
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.

The vertical sequence of the layers of soil is called a soil?
The vertical sequence of soil layers is called a soil profile. This profile typically consists of distinct layers, or horizons, that vary in color, texture, and composition. It is important for understanding the different properties and characteristics of the soil.
Why As you dig a hole you see layers of soil with different colors in content what are these layers called?
The layers of soil with different colors and content are called soil horizons. These horizons are classified into layers like topsoil, subsoil, and bedrock based on factors such as color, texture, and composition. They provide valuable information about the soil's composition, fertility, and history.
Horizontal layers of soil What is the answer?
Horizontal layers of soil are called soil horizons, which are distinct layers that form as a result of different processes happening within the soil over time. These horizons are identified based on differences in color, texture, structure, and composition.
What is soil horizonation?
Soil horizonation refers to the different layers, or horizons, that make up a soil profile. These layers are differentiated based on their composition, color, texture, and other characteristics. By studying soil horizonation, scientists can better understand the formation and properties of soil.
What is the definition of soil profile?
A soil profile is a vertical section of soil layers that shows the different horizons (layers) from the surface down to the parent material. It provides information about the composition, structure, and characteristics of the soil at a particular location.

What is permeabillity of soil?
Permeability is the rate (speed) that rainwater seeps through the different layers of soil.

A soil profile is a vertical section of soil layers that shows the different horizons (layers) from the surface down to the parent material. It provides information about the composition, structure, and characteristics of the soil at a particular location.
A vertical section of soil that shows the layers?
A vertical section of soil that shows the layers is called a soil profile. It typically includes distinct layers, or horizons, such as topsoil, subsoil, and bedrock, each with different characteristics and compositions. Soil profiles provide valuable information about the history, composition, and fertility of the soil.
Write a short notes on soil profile?
soil is the earth and it supports us in staing alive.
Is soil horizon a layer of soil?
When soil is cut vertically different layers are seen called horizons which are named A ,B ,C etc.
Why do soil profiles contain layers?
Soil profiles contain layers because of the different processes that contribute to soil formation, such as weathering, organic matter accumulation, and soil organisms activity. Each layer represents a distinct stage in soil development and can provide information about the history and characteristics of the soil.
Why does soil settle into layers?
Soil settles into layers due to the process of soil formation, where different particles and organic matter accumulate over time. Gravity causes heavier particles to settle at the bottom, forming distinct layers based on their size and composition. This layering process is known as soil horizonation and influences soil properties and fertility.
What is a vertical picture of all the layers of soil?
A vertical picture of all the layers of soil is called a soil profile. It shows the different layers or horizons of soil, such as topsoil, subsoil, and bedrock, and provides information on the composition and characteristics of each layer. Soil profiles are important for understanding soil properties and processes that affect plant growth and environmental quality.
