What are the layers of soil found on the Earth?
Layers are also know as Horizons....You have:The A Horizon, (Topsoil) has more humus.Litter= Layers of leaves, twigs, or other organic matter that will be turned in to humus, this prevents erosion and evaporation of water from the soil.The B Horizon, (Subsoil) has less organic matter (less humus), lighter in color, less fertile.The C Horizon, Consists of partially weathered rock, does not contain much organic matter, below the C Horizon is solid parent rock.
How many layers of soil?
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)
How scientist classify soils?
In three layers/horizons:A (made of topsoil, crumbly, dark brown soil mixture of humus, clay, and other minerals.)B (made of subsoil, made of clay and other particles with little humus.)andC (contains partly weathered rock.)Read more: How_do_scientists_classify_soil
Does subsoil contain more organic matter than topsoil or parent rock?
yes
How do scientist classify soils?

What are the three layers that form the soil profile?
The three layers that form the soil profile are topsoil, subsoil, and bedrock. Topsoil is the uppermost layer rich in organic matter and nutrients, while subsoil is the middle layer with less organic material and more minerals. Bedrock is the solid rock layer found beneath the soil layers.
Does subsoil contain more organic matter than either topsoil or parent rock?
Subsoil generally contains less organic matter than topsoil because organic matter tends to accumulate near the surface where plants and organisms are active. Parent rock typically has minimal organic matter.
Why is Horizon B called subsoil?
Horizon B is called subsoil because it is the layer of soil located beneath the topsoil (Horizon A) and above the parent material (bedrock or unweathered rock). Subsoil often contains less organic matter and nutrients compared to topsoil, making it less fertile for plant growth.
Is it true Unweathered rock that underlies soil is subsoil.?
No, unweathered rock that underlies soil is typically referred to as bedrock, not subsoil. Subsoil is the layer of soil beneath the topsoil that is rich in minerals and nutrients.
What is in each layer of soil?
The soil is typically divided into three main layers: topsoil, subsoil, and bedrock. Topsoil is the uppermost layer rich in organic matter, nutrients, and microorganisms. Subsoil lies beneath the topsoil and consists of less organic matter but more minerals. Bedrock is the solid rock layer that underlies the subsoil and serves as the parent material for the soil above.
What are the 3 main layers in mature residual soils?
The three main layers in mature residual soils are the topsoil, which is rich in organic matter and nutrients, the subsoil, which contains less organic matter and may have distinct characteristics from the topsoil, and the parent material, which is the unaltered rock or minerals from which the soil developed.
What is sub soil water?
Subsoil water is water that is located below the uppermost soil layer, known as topsoil, in the ground. It is found in the layer of soil beneath the topsoil and contributes to groundwater recharge. Subsoil water is essential for sustaining plant growth and maintaining soil moisture levels.
