Which soil layer is least similar to the underlying rock?
The topsoil layer is typically least similar to the underlying rock because it is composed of organic matter, minerals, and nutrients that have been weathered and mixed over time. This layer is influenced by factors such as climate, vegetation, and erosion, making it different in composition from the solid rock below.
Which layer of a soil profile forms first from the bedrock?
The C horizon is the layer of a soil profile that forms first from the bedrock. It is the underlying layer that contains weathered rock fragments and shows the least amount of soil development.
Which layer of soil is least likely to be penetrated by plant roots?
The parent rock layer is least likely to be penetrated by plant roots due to its hard and compact nature. Roots typically grow in the upper layers of soil where there is more organic matter and nutrients available for plant growth.
What is the name of the bottom rock layer?
The bottom layer of a sedimentary rock is called the basal layer. This layer is considered the coarsest in the rock.
Is bedrock the layers of rock above soil?
Bedrock is solid rock underlying the loose surface deposits like soil or alluvium. It is the lowest layer of rock that makes up the Earth's crust and provides a stable foundation for soil and other materials above it.

Which soil layer is most similar to underlying rock?
bedrock
Which layer of a soil profile forms first from the bedrock?
The C horizon is the layer of a soil profile that forms first from the bedrock. It is the underlying layer that contains weathered rock fragments and shows the least amount of soil development.
What is the mechanical layer of earth that is solid rock and moves the least crust lithosphere?
The mechanical layer of Earth that is solid rock and moves the least is the lithosphere. It comprises the Earth's crust and the uppermost part of the mantle, forming a rigid outer shell. The lithosphere is divided into tectonic plates that can move, but the individual rocks within this layer are generally stable and do not flow like those in the underlying asthenosphere.
When A glacier will move by sliding when the base of the ice and the underlying rock are separated by a thin layer of?
I believe the answer is water.
Which layer of soil is least likely to be penetrated by plant roots?
The parent rock layer is least likely to be penetrated by plant roots due to its hard and compact nature. Roots typically grow in the upper layers of soil where there is more organic matter and nutrients available for plant growth.
What is the name of the bottom rock layer?
The bottom layer of a sedimentary rock is called the basal layer. This layer is considered the coarsest in the rock.
Why is the C horizon the least evolved layer of soil?
The C horizon contains only party weathered rock.
What horizon is the deepest?
The deepest soil horizon is typically the C horizon, also known as the "parent material." This layer is composed of unweathered rock or partially weathered rock from which the upper layers of soil are formed. Below the C horizon lies the bedrock, which is not considered a soil layer but rather the solid rock underlying the soil profile.
What layer of the earth is the solid rock layer?
The lithosphere is the physical layer of hard brittle rock. The remainder of the mantle that is not contained in the lithosphere is the layer of ductile rock.
To date a sedimentary rock layer between two igneous rock units geologists use radiometric dating and assume that the sedimentary layers are?
Geologists use radiometric dating of the igneous rock units above and below the sedimentary layer to establish a time range for the sedimentary rock. They assume that the sedimentary layers are younger than the underlying igneous rock and older than the overlying igneous rock, based on the principle of superposition. This allows them to estimate the age of the sedimentary layer by determining the ages of the surrounding igneous rocks.
What is rock layers?
rock layering is where you have one layer of old rock them a newer layer then an other newer layer.
